1 Timothy 1:15
Here is a trustworthy saying that deserves full acceptance: Christ Jesus came into the world to save sinners—of whom I am the worst.

The Jewish apostle Paul wanted his fellow Jewish brothers to believe that Jesus was the Messiah. Paul tells us about his struggle with his sinful nature. There is a constant battle going on. And the faithful Apostle admits that He keeps on making mistakes after being saved. Thats why He writes that He «is» the worst of sinners. Not that he «was» the worst of sinners. Paul always considers others better than him self. We should try to follow his example.
