5 This is the message we have heard from him and proclaim to you, that God is light, and in him is no darkness at all.6 If we say we have fellowship with him while we walk in darkness, we lie and do not practice 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 cleanses us from all sin.8 If we say we have no sin, we deceive ourselves, and the truth is not in us.9 If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.
Isaiah 45
6 that people may know, from the rising of the sun and from the west, that there is none besides me; I am the LORD, and there is no other.
John 1
5 The light shines in the darkness, and the darkness has not overcome it.
Psalm 84
11 For the LORD God is a sun and shield; the LORD bestows favor and honor. No good thing does he withhold from those who walk uprightly.
