Where is it found that “the fight is between God & Satan” and that “the fight is not ours.”

Answer:

Part of the battle is ours…James 4:7  Submit yourselves therefore to God. Resist the devil, and he will flee from you.

God did come to earth so that we are guaranteed of the outcome if we side with him.

1 John 3:8  He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil.
