The fact of God’s existence is so conspicuous, both through creation and through man’s conscience, that the Bible calls the atheist a “fool” (Psalm 14:1). The Bible never attempts to prove the existence of God; rather, it assumes His existence from the very beginning (Genesis 1:1). The Bible reveals the nature, character, and work of God.
Numbers 23:19
19. God is not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do it? or hath he spoken, and shall he not make it good?
Malachi 3:6
6. For I am the Lord, I change not; therefore ye sons of Jacob are not consumed.
John 4:24
24. God is a Spirit: and they that worship him must worship him in spirit and in truth.
