1 John 1:5-10 –5 This is the message we have heard from him and declare to you: God is light; in him there is no darkness at all. 6 If we claim to have fellowship with him yet walk in the darkness, we lie and do not live by the truth. 7 But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus, his Son, purifies us from all sin.
8 If we claim to be without sin, we deceive ourselves and the truth is not in us. 9 If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness. 10 If we claim we have not sinned, we make him out to be a liar and his word has no place in our lives.
God and Jesus are Truth and Light.
Darkness is a place further from God. The further you get the darker it gets. Lies are the same way. The further you get the worse the lies get.
I really enjoy how the above verses tell us we need to walk in Light, but we are not to kid ourselves into thinking we are without sin. Still choosing to walk in darkness is a bad ploy. We are not to abuse the grace on purpose. The more we tread out in the darkness, the harder it is to understand the Truth.
