Light cannot ever coincide darkness (duh). Whenever light enters a dark space, it repels the darkness around it. They can never be together; its either one or the other.
God is holy. He is always pure and righteous. In fact the Bible describes Him as light:
“This is the message we heard from Jesus and now declare to you: God is light, and there is no darkness in him at all.” – 1 John 1:5
Sin is not God’s vocabulary, and like light to darkness, He also can’t coincide with it. Sin separates us from God (Isaiah 59:2). Size doesn’t matter. Once you have sinned, you have broken fellowship with God.
As Romans 3:23 stated, “all have sinned”; at one time in our lives we have fallen short of God’s glory, and therefore we are repelled from relating to God.
“And you, who once were alienated and enemies in your mind by wicked works, yet now He has reconciled in the body of His flesh through death, to present you holy, and blameless, and above reproach in His sight. ” -Colossians 1:21-22
It was by the blood of Jesus on the cross that we are removed of sin’s power and punishment over our lives and now we can have fellowship with God.
“But if we walk in the light as He is in the light, we have fellowship with one another, and the blood of Jesus Christ His Son cleanses us from all sin.” -1 John 1:7
God desires intimacy with us. To keep healthy intimacy with God, we must “walk in the light”.
If we truly desire to be intimate with Him then we must seek to be in the light as He is in the light; that is being removed from the presence of sin and seeking to be filled of righteousness.
