All People Know who God is.
John 1:9 That was the true Light, which lighteth every man that cometh into the world.
Rom 1:18 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness; Rom 1:19 Because that which may be known of God is manifest in them; for God hath shewed it unto them. Rom 1:20 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:
John 3:16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. John 3:17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved. John 3:18 He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God. John 3:19 And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil. John 3:20 For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved. John 3:21 But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God.
2Pet 3:3 Knowing this first, that there shall come in the last days scoffers, walking after their own lusts, 2Pet 3:4 And saying, Where is the promise of his coming? for since the fathers fell asleep, all things continue as they were from the beginning of the creation. 2Pet 3:5 For this they willingly are ignorant of, that by the word of God the heavens were of old, and the earth standing out of the water and in the water: 2Pet 3:6 Whereby the world that then was, being overflowed with water, perished: 2Pet 3:7 But the heavens and the earth, which are now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men.
