Not true. There are still people to become Christians. That does not indicate they currently hate God. Some have never heard of God.
Romans 2:14-15
For when Gentiles who do not have the Law do instinctively the things of the Law, these, not having the Law, are a law to themselves, in that they show the work of the Law written in their hearts, their conscience bearing witness and their thoughts alternately accusing or else defending them.
John 15:18
If the world hates you, you know that it has hated Me before it hated you.
Romans 3:9-12
What then? Are we better than they? Not at all; for we have already charged that both Jews and Greeks are all under sin; as it is written, “THERE IS NONE RIGHTEOUS, NOT EVEN ONE; THERE IS NONE WHO UNDERSTANDS, THERE IS NONE WHO SEEKS FOR GOD; ALL HAVE TURNED ASIDE, TOGETHER THEY HAVE BECOME USELESS; THERE IS NONE WHO DOES GOOD, THERE IS NOT EVEN ONE.”
Before we come to God..we all sin and hate God.
