Christ is our savior, and the only reason we have needed mercy for eternal salvation

"This is a faithful saying and worthy of all acceptance, that Christ Jesus came into the world to save sinners, of whom I am chief. However, for this reason I obtained mercy, that in me first Jesus Christ might show all longsuffering, as a pattern to those who are going to believe on Him for everlasting life." 1 Timothy 1:15-16, NKJV
