Thank you, dear sister.

I think I called this out in another thread.

If "chief" was meant to be understood as sequential/order as in Paul being the first sinner to be saved by our Lord Jesus Christ into the one body, then the Holy Spirit would have led Paul to write "of whom I am first."  But the Spirit did not.

Because we see in the preceding verse, when referencing Christ showing all longsuffering in Paul, God actually used the word, "first" there to denote sequence/order.

But when referring to Paul as a sinner, it says he is "chief."

So it's clear that 'first' and 'chief' are not the same here (as we see in the two adjacent verses).

Christ showed all longsuffering in Paul first, who is the chief of sinners.

We also see in the context, Paul listed how he is distinctly the chief of sinners (at the time he was saved by our Lord Jesus Christ): He was a blasphemer, persecutor, and injurious/insolent man.

No one persecuted the Lord Jesus Christ and His church as Saul/Paul did at that time.

Yet our Lord Jesus Christ is so kind, gracious, and merciful to save Paul.

I appreciate your labor of love, beloved sister.
