odd would be if the true God was evil and so there was no difference between the "Light" and the "darkness"
Genesis 1:3-31 "And God said, Let there be light: and there was light. And God saw the light, that it was good: and God divided the light from the darkness. And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day..... And God saw every thing that he had made, and, behold, it was very good(i.e. it was absolutely good and not a bit evil). And the evening and the morning were the sixth day.",
1 John 1:5-10 "This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all. If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth: But if we walk in the light, as he is in the light, we have fellowship one with another(i.e. then we have benevolence/friendliness towards the others), and the blood of Jesus Christ his Son cleanseth us from all sin. If we(i.e. but if we sinning) say that we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins(i.e. however if in such circumstances we confess that the fault is our and not of God), he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. If(i.e. but if) we say that we have not sinned, we make him a liar, and his word is not in us.",
1 John 2:9-11 "He that saith he is in the light, and hateth his brother, is in darkness even until now. He that loveth his brother abideth in the light, and there is none occasion of stumbling in him. But he that hateth his brother is in darkness, and walketh in darkness, and knoweth not whither he goeth, because that darkness hath blinded his eyes.",
1 John 3:14-15 "We know that we have passed from death unto life, because we love the brethren. He that loveth not his brother abideth in death. Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him."
