Genesis 3: 4-5 And the serpent said unto the woman, Ye shall not surely die: for God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil.
After Adam willfully disobeyed the commandment of God and took of the tree of the knowledge of good and evil his attitude toward God and toward himself changed. The moment Adam and Eves eyes were opened they knew they were naked (Gen. 3:7). When Adam saw himself the way God made him he did not see a wonderful creation. He did not rejoice in the miracle of life breathed into his nostrils from God. Instead, the lusts of the flesh filled his heart. The vanity of the flesh consumed him and he was ashamed. Whereas before he went about with no sin, full of the joy of all creation bestowed upon him by God the Creator, now, full of evil, he was not content with Gods way. God said of his creation, It is good. Adam said of Gods creation, I can do better. Thinking himself to be a god he began to devise his way. All the while unaware of this one dreadful thing, that all his thoughts were now turned away from God and only toward himself. Every person born in Adam receives this same nature that Adam obtained. And just as Adam did, man crowns himself king, always bending the truth of the one true God into the god of his imaginationa god like unto himself.
In thinking himself a god, Adam feared the true God. When Adam heard the voice of the Lord God walking in the garden Adam and his wife hid themselves from the presence of the Lord God amongst the trees of the garden. (Gen. 3:8) Adam feared that God would discover the evil, which he had done. Adams sin separated him from God. All the sweet fellowship he once had with the Lord God was ended. There is within every spiritually dead man the knowledge that God is good and that fallen man is evil. But rather than beg God for mercy and grace, the man who thinks himself a god hides away, for fear that he will have to confess what he is. This is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil. For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved.
