Paul was NOT the "Chief" of Sinners!
Paul is NOT Condoning sin, neither is he the ‘Chief of sinners’ so many wrest to their destruction not dividing the word of truth correctly! Full teaching here https://goo.gl/rC5Ha2
1 Timothy 1:15 "This is a faithful saying, and worthy of all acceptation, that Christ Jesus came into the world to save sinners; of whom I am CHIEF(G4413)."
CHIEF in the Greek = G4413 πρῶτος prōtos pro'-tos [PROTOTYPE] Contracted superlative of G4253; FOREMOST(in time, place, order or importance): - BEFORE, beginning, best, chief (-est), first (of all), FORMER. [Total KJV occurrences: 100]
If you believe you are saved in sin, repent and go to The Way to The Cross https://goo.gl/Qetm4H. Then read What is Biblical Perfection https://goo.gl/vepJ4P.
