You have a reading problem 1 Timothy 1:16 KJV
1Ti 1:16 Howbeit for this cause I obtained mercy, that in me first Jesus Christ might shew forth all longsuffering, for a pattern to them which should hereafter believe on him to life everlasting.
1Ti 1:
The word translated first in greek, means before-most or foremost.
It does not mean that Paul was the first to show forth the longsuffering of Christ in him.
Many of the apostles and others at the first suffered for the name of Christ before Paul did.
and Paul walked and suffered with Christians who were saved before he was.
What did Paul add to the gospel of Christ?
Nothing.
Paul was an example to all who would suffer for the name of Christ after him among the nations.
However all the apostles suffered that way as Paul had said--
1Co 4:9 For I think that God hath set forth
us the apostles last, as it were appointed to death: for
we are made a spectacle unto the world, and to angels, and to men.
1Co 4:10
We are fools for Christ's sake, but ye are wise in Christ; we are weak, but ye are strong; ye are honourable, but we are despised.
1Co 4:11 Even unto this present hour
we both hunger, and thirst, and are naked, and are buffeted, and have no certain dwellingplace;
1Co 4:12 And labour, working with our own hands: being reviled, we bless; being persecuted, we suffer it:
1Co 4:13 Being defamed,
we intreat: we are made as the filth of the world, and are the offscouring of all things unto this day.
1Co 4:14 I write not these things to shame you, but as my beloved sons I warn you.
1Co 4:15 For though ye have ten thousand instructors in Christ, yet have ye not many fathers: for in Christ Jesus I have begotten you through the gospel.
1Co 4:16 Wherefore I beseech you, be ye followers of me.
(as Paul follows Christ)
1Co 11:1 Be ye followers of me, even as I also am of Christ.
