Why would Calvinists assured of going to Heaven need to obey that passage or any other passage since they'll be going to Heaven no matter what? Why bother to correct people who are going to be damned no matter what?2 Timothy 4:2 KJV
[2] Preach the word; be instant in season, out of season; reprove, rebuke, exhort with all longsuffering and doctrine.
