We did hate God, thats why god sent men across the world to show us our failure and our hate, why he sent the hs to convict us, and why he uses creation to show us we have no excuse.
We hate god because we want to be god, repentance is what happens when we realise we have failed, and will continue to fail, thats why no matter what i try, my life sucks, thats why god is patient, willing that no one should perish, because if he removed all suffering from earth and gave mankind this great fulfilling life no one would come to him
If you talk to believers you will hear many different testimonies of how god brouht them to faith. And all the things (including pain and suffering for many) which caused them to seek God, and as god promised, if you seek, he will make sure you find. What he does not promise is if you find, you will believe, many find, and never recieve, and eventually walk away, because they had no root.
