All know that God exists. But some choose to repent and put their faith in God, and many choose not to. Roman 1:20 says: 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:
The fool hath said in his heart, There is no God. They are corrupt, they have done abominable works, there is none that doeth good. (Psalm 14:1)
For those of you who don't want to repent, soften your heart, humble your heart, ask God to help you recognise your sin and repent. I don't want to ending up in hell. Heed my words.
