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.
Let your good works be seen, but for the sole purpose of drawing attention to the Father.
