When sinners have a chance they will try to murder God. John 8:36 If the Son therefore shall make you free, ye shall be free indeed. 37 I know that ye are Abraham's seed; but ye seek to kill me, because my word hath no place in you. 40 But now ye seek to kill me, a man that hath told you the truth, which I have heard of God: this did not Abraham. 44 Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. 58 Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am. 59 Then took they up stones to cast at him: but Jesus hid himself, and went out of the temple, going through the midst of them, and so passed by. The knowledge of God (along with his eternal power) is immediately known to all men by the revelation of his works in creation. (Rom.1:19-21, Psa.19:1-3) The problem is that “they did not like to retain God in their knowledge” (Rom.1:28) “they hated knowledge, and did not choose the fear of the Lord” (Prv.1:29) and “they are all under sin”. (Rom.3:9) As it is written, There is none righteous, no, not one: There is none that understandeth, there is none that seeketh after God. They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one. (Rom.3:10-18) They are haters of God (Rom.1:30) and thus murderers of God (1 Jn.3:15, Jam.4:4, Jn.8:40, 58-9, 3:19-20). They hate and therefore deny his particular existence. Thus when they speak of a God you are speaking of a figment of your imagination. You are doing exactly as Paul stated- they “changed the glory of the uncorruptible God into an image made like to corruptible man” and again “changed the truth of God into a lie, and worshipped and served the creature more than the Creator” (Rom.1:23,25). You are rejecting his revelation, denying his existence and creating in his place a god in your heart that is more appealing and desirable because it is like you (Ezek.14:3-4, 8:12). You then become the prophet of this god knowing what he will and won’t do; what he likes and dislikes, delivering his commandments. Now imagine that the God of scripture is real and he says that he is immediately known to all people from his creation to the degree “that they are without excuse” (Rom.1:20). And you, his creature, deny his existence, call him a liar in that you declare his revelation is not clear and that you do have an excuse. But yet you do not seek him to find out the knowledge of the holy, rather you employ your energies and time in gratifying your lusts, defiling your body, mind and conscience (Rom.1:24-32, Tit.1:15) and go whoring after devils (Lev.17:7,Psa.106:37). Which is to say you permanently alter yourself to the negative after having been given by him invaluable resources such as your eyes, your speech, your mind, love, life, time, hearing, tasting, feeling, beauty. Were you thankful to him? No (Rom.1:21), you denied his existence and stamped out every mention of him, turning your ear at every thought of him and thereby becoming forever his enemy.
