There are many biblical passages teaching us why we must “walk in the light.” (This would include avoiding friends who would influence us to “walk in the dark.”) Read on…
“God is light, and in him is no darkness at all. If we say we have fellowship with him while walking in darkness, we lie and do not practice the truth. But if we walk in the light as he is in the light, we have fellowship with one another…” (1 John 1:5-7)
“For you were once darkness, but now you are light in the Lord. Live as children of light… [that you me be able to] discern what is pleasing to the Lord.” (Ephesians 5:8, 10)
It’s clear why God chose to so often use the metaphor of light: it’s hard to find our way in the dark physically. It’s impossible to find our way in the dark spiritually.
Further, and significantly, there is added blessing to walking in the light of Christ: as believers walk in the light of the truth, the knowledge of the Lord’s will becomes clear.
We obey: God blesses.
