1 Timothy 1:13-16

though I was before a blasphemer, and a persecutor, and injurious: howbeit I obtained mercy, because I did it ignorantly in unbelief; and the grace of our Lord abounded exceedingly with faith and love which is in Christ Jesus. Faithful is the saying, and worthy of all acceptation, that Christ Jesus came into the world to save sinners; of whom I am chief: howbeit for this cause I obtained mercy, that in me as chief might Jesus Christ show forth all his longsuffering, for an ensample of them that should thereafter believe on him unto eternal life.
