FOUR reasons I believe in the sinful nature. (original sin/ancestral sin/total depravity)

Sure.

Physically existing is colloquially called life.

This is why Jesus told us what "true" or "real" life is, which gives greater precedence and authenticity to spiritual life over physical existence.

If you can't see that, you will never appreciate what grace really means, and exalt naturalism over redemption.

We all exist beyond the physical. Death isn't the absence of existence.

To many, this is the only the life they will ever know. This is God's grace to all men.

Act 17:25 Neither is worshipped with men's hands, as though he needed any thing, seeing he giveth to all life, and breath, and all things;

Act 17 contains one of the shortest yet deepest sermons Paul ever preached. It changed my life the day I started paying attention to what he said.

It is the life that is afforded all of humanity that leads men to God. This life is designed to teach us. It is all that is left for rebels that deny God like we've done in our past.
