Walking in the Light

A devotional on 1 John 1:5–10

The foundation

“God is light, and in Him is no darkness at all.” — 1 John 1:5

John begins with who God is. God does not merely possess light; God is light. He is completely holy, true, and good. There is no deceit, moral darkness, or hidden evil in him.

Because God is light, fellowship with him must affect how we live. John therefore gives us five “if” statements. Each one invites us to examine whether our words and our way of life agree.

The five “ifs”

IFRealityConsequence
If we claim to have fellowship with God while walking in darkness (v.6)Our conduct contradicts our claim.We lie and do not practice the truth.
If we walk in the light, as God is in the light (v.7)We live openly before God and allow His truth to shape us.We enjoy fellowship, and Jesus’ blood cleanses us from all sin.
If we claim to have no sin (v.8)We deny our present sinful condition.We deceive ourselves, and the truth is not in us.
If we confess our sins (v.9)We agree with God about our sin instead of hiding or excusing it.God faithfully and justly forgives and cleanses us.
If we claim that we have not sinned (v.10)We reject God’s testimony about our guilt and need.We make God out to be a liar, and his word is not in us.

Walking in the light does not mean being perfect

It would be easy to read this passage and conclude that walking in the light means never stumbling or sinning. But John immediately warns us against claiming to be without sin.

A person walking in darkness hides, excuses, or denies sin. A person walking in the light brings sin before God, calls it what God calls it, and trusts Christ for cleansing. The difference is not that one person needs grace while the other does not. The difference is that one hides from grace while the other steps into it.

Light exposes what is wrong, but its purpose is not merely to shame us. God’s light leads us to the cleansing that is found in Jesus.

Two responses to sin

False response to sinTrue response to sin
Claiming fellowship while continuing comfortably in darknessWalking openly before God
Hiding or excusing sinAllowing God’s light to expose it
Claiming to have no sinful natureAcknowledging our continuing need for grace
Claiming never to have sinnedConfessing our particular sins
Depending on appearancesDepending on Christ’s cleansing
Results in deception and broken fellowshipResults in forgiveness, cleansing, and restored fellowship

The danger of spiritual claims

Three times John speaks about what “we say.” We may say that we know God, that we have no sin, or that we have not sinned. But our words do not determine spiritual reality.

John asks us to look beyond our claims:

  • Does my conduct agree with my confession?
  • Am I willing to let God’s truth examine me?
  • Do I admit my sin, or do I instinctively defend myself?
  • Am I living openly before God and other believers?

Christian faith is more than saying the right things. It is living truthfully in the presence of God.

The promise of confession

“If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.” — 1 John 1:9

God’s response rests on his character:

  • He is faithful: He keeps His promise to forgive.
  • He is just: Christ has dealt with the guilt of our sin.
  • He forgives: our guilt is removed.
  • He cleanses: He works against sin’s pollution and power in us.

We do not confess to persuade a reluctant God to be merciful. We confess because God has already provided cleansing through Jesus Christ.

Fellowship in the light

Walking in the light also produces “fellowship with one another.” When we hide from God, we often hide from people as well. We protect an image, fear being known, and keep others at a distance.

Grace gives us the freedom to be honest. We no longer need to pretend that we have no struggles. Christian fellowship grows when believers can say, “I need Christ’s mercy too.”

This does not mean sharing everything with everyone. It means abandoning hypocrisy and developing relationships marked by truth, humility, forgiveness, and grace.

Questions for reflection

  1. Is there an area of my life that I am trying to keep out of God’s light?
  2. Am I excusing, minimizing, or blaming someone else for a particular sin?
  3. Do my daily choices support my claim to have fellowship with God?
  4. When God exposes sin, do I hide in shame or come to Christ for cleansing?
  5. Is pride preventing me from being honest with another trustworthy believer?
  6. What would one practical step of “walking in the light” look like today?

A practice for today

Take a few quiet moments with God.

  1. Ask the Holy Spirit to search your heart.
  2. Name specifically whatever He brings to your attention.
  3. Accept responsibility without defending or excusing yourself.
  4. Thank God that forgiveness rests on Christ’s work, not your worthiness.
  5. Ask for strength to make any necessary change, apology, or restitution.
  6. Walk forward in the freedom of being fully known and deeply loved.

Father, you are light, and there is no darkness in you. Shine your light into every part of my heart. Show me where my actions do not agree with my words and where I have hidden, excused, or denied my sin.

Give me the humility to confess honestly and the faith to receive the forgiveness you have provided through Jesus. Thank you that you are faithful and just to forgive me and to cleanse me from all unrighteousness.

Help me to walk openly before you today. May my life be shaped by your truth, my relationships be marked by genuine fellowship, and my confidence rest in the cleansing blood of Jesus. Amen.

Affliction Over Splendour: A Daily Imperative for Disciples

In Scripture, clearer passages often illuminate the more obscure, a foundational principle for understanding. Here, two texts converge to reveal this dynamic at work: one outlines the call to discipleship, while the other embodies it in the life of Moses—an archetype of Christ—answering the pressing question: What does this look like in practice?

The first passage, Luke 9:23–27, lays out Jesus’ unmistakable imperative for His followers:

And He said to all, “If anyone would come after me, let him deny himself and take up his cross daily, and follow me. For whoever would save his life will lose it, but whoever loses his life for my sake will save it. For what does it profit a man if he gains the whole world and loses or forfeits himself? For whoever is ashamed of Me and of My words, of him will the Son of Man be ashamed when He comes in His glory and the glory of the Father and of the holy angels. But I tell you truly, there are some standing here who will not taste death until they see the kingdom of God.”

This is no singular event but a daily rhythm of surrender, renewed each morning like God’s mercies (Lamentations 3:22–23). It’s a lifelong commitment to self-denial, not for asceticism’s sake, but for the sake of following Christ into true life.

To grasp its shape or form, we turn to Moses’ story in Hebrews 11:23–28, a vivid parallel:

By faith Moses, when he was born, was hidden for three months by his parents, because they saw that the child was beautiful, and they were not afraid of the king's edict. By faith Moses, when he was grown up, refused to be called the son of Pharaoh's daughter, choosing rather to be mistreated with the people of God than to enjoy the fleeting pleasures of sin. He considered the reproach of Christ greater wealth than the treasures of Egypt, for he was looking to the reward. By faith he left Egypt, not being afraid of the anger of the king, for he endured as seeing Him who is invisible. By faith he kept the Passover and sprinkled the blood, so that the Destroyer of the firstborn might not touch them.

Raised as Pharaoh’s adopted grandson, Moses enjoyed unparalleled privilege—wealth, power, and the splendour of Egypt (Exodus 2:11–15). Yet he renounced it all, identifying instead with his enslaved Hebrew kin. This meant exile, hardship, and rejection: fleeing after killing an Egyptian oppressor, wandering as a fugitive, and embracing the shame of solidarity with the afflicted. In choosing Israel’s suffering over Egypt’s fleeting pleasures, Moses valued the “reproach of Christ” as surpassing treasure, eyes fixed on an unseen reward.

This choice foreshadows Christ’s own descent: leaving heavenly glory to share in humanity’s reproach—betrayal, scorn, and the cross (Isaiah 53:3; Hebrews 12:2). Just as Moses traded visible riches for invisible hope, disciples are summoned daily to “take up the cross,” forsaking self-preservation for alignment with Christ’s redemptive mission. Both stories recast loss as eternal gain: apparent defeat yielding resurrection life.

The parallels between Jesus’ words in Luke and Moses’ life in Hebrews reveal a timeless pattern of faith: costly obedience that prioritizes eternal reward over temporal security. Here’s how they align:

AspectLuke 9:23-27 (Jesus’ Call)Hebrews 11:23-28 (Moses’ Faith)Shared Theme
Self-Denial“Deny himself” and lose life to save it (v. 23-24).Refused Pharaoh’s privileges for mistreatment with God’s people (v. 25).Both reject worldly status/comfort for God’s path.
Embracing Suffering“Take up his cross daily” (v. 23).Endured as “seeing him who is invisible” (v. 27).Faith sustains through visible trials by focusing on the unseen God.
Reproach/ShameNot be “ashamed” of Jesus (v. 26).Considered “the reproach of Christ” greater than Egypt’s treasures (v. 26).Willingness to bear scorn for alignment with Christ/God’s people.
Eternal PerspectiveGain soul over world; see kingdom of God (v. 25, 27).Looked to “the reward” beyond fleeting pleasures (v. 26).Short-term loss yields long-term gain in God’s kingdom.
Active Obedience“Follow me” daily (v. 23).Left Egypt; kept Passover (v. 27-28).Faith manifests in bold, communal actions of loyalty.

For believers today, this convergence of cross and reproach calls us to live counter-culturally amid a world that often ridicules faith. The cross is no mere historical emblem of atonement but an active summons to share Christ’s sufferings (Colossians 1:24; 1 Peter 4:13). It manifests in two intertwined realities:

 Personal Sacrifice: Echoing Moses’ rejection of Pharaoh’s luxuries and Jesus’ call to self-denial, we might relinquish career ambitions, social status, or material ease to pursue justice, generosity, or witness. In our consumerist era, this could involve downsizing for the sake of the marginalised—opting for “mistreatment with the people of God” over sin’s passing allure.

 Enduring Opposition: The reproach of public shame ties directly to the cross’s cost (Luke 9:26). Contemporary echoes include workplace bias for ethical choices, digital backlash for gospel truths, or familial rifts over conviction. Yet, like Moses, we count this “reproach of Christ” (Hebrews 11:26) as immeasurable wealth—vindicated at His return and fostering intimacy with God in the present.

What binds these threads for us is a transformative hope: the cross and reproach are not futile wounds but gateways to renewed life. They forge character through suffering (Romans 5:3–5), knit us into the global church amid persecution, and point to the kingdom where every knee bows (Philippians 2:10). In daily practice, this unfolds through prayerful yielding, bold proclamation, and mutual encouragement—mirroring Moses’ steadfast gaze and Jesus’ obedient path. As He promises, those who lose their lives for His sake will truly find it.

Let your light shine!

Jesus declares one of His “I am” statements in John 8: 12. “I am the light of the world. Whoever follows me will never walk in darkness, but will have the light of life.”

Whoever obeys Jesus will walk in the light and will have the light of life, life eternal.

Another key reference is John 1:4-5: “In Him was life, and that life was the light of all mankind. The light shines in the darkness, and the darkness has not overcome it.”

Then He declares in Matthew 5:16, (we who obey) you are the light of the world (because you have the light in you). “You are the light of the world. A city set on a hill cannot be hidden; nor do people light a lamp and put it under a basket, but on the lampstand, and it gives light to all who are in the house.

Finally He commands us in the same passage further on in verse 16, “Your light must shine before people in such a way that they may see your good works, and glorify your Father who is in heaven” . 

Let this light shine before people NOT to draw attention to us, but to the Father, that the Father may be glorified. When our light shines in this way, in particular drawing attention to the Father, then He will be glorified. People can only glorify God if they have come to know Him. In other words God’s kingdom is being established by the light that shines through our speech and actions (good works). People need to see the light in us.

So don’t hide the light!

A final word from Daniel 12:3(ESV). And those who are wise shall shine like the brightness of the sky above; and those who turn many to righteousness, like the stars forever and ever.
