And the one guarding His commandments abides in Him and He in him. And by this we experientially know that He abides in us, out from the Spirit who He gave us. 1 John 3:24
But if perhaps we walk in the light, as He is in the light, we have fellowship with one another and the blood of Jesus His Son keeps on cleaning us from all sin.
And this is the message which we heard from Him and announce to you, that the God is light and there is no darkness in Him.
