A.T. Robertson Commentary Colossians 4:12

"Epaphras, who is one of you, a servant of Christ Jesus, saluteth you, always striving for you in his prayers, that ye may stand perfect and fully assured in all the will of God." — Colossians 4:12 (ASV)

Epaphras who is one of you (Επαφρας ο εξ υμων). See 1:7 for previous mention of this brother who had brought Paul news from Colossae.

Always striving for you (παντοτε αγωνιζομενος υπερ ημων). See 1:29 of Paul.

That ye may stand (ινα σταθητε). Final clause, first aorist passive subjunctive (according to Aleph B) rather than the usual second aorist active subjunctives (στητε) of ιστημ (according to A C D).

Fully assured (πεπληροφορημενο). Perfect passive participle of πληροφορεω, late compound, for which see Lu 1:1; Romans 14:5.
