A.T. Robertson Commentary James 2:22

"Thou seest that faith wrought with his works, and by works was faith made perfect;" — James 2:22 (ASV)

Thou seest (βλεπεις). Obvious enough with any eyes to see. This may be a question, seest thou?

Wrought with (συνηργε). Imperfect active of συνεργεω, old verb for which see Ro 8:28. Followed by associative-instrumental case εργοις. Faith cooperated with the deed of offering up Isaac.

Was made perfect (ετελειωθη). First aorist passive indicative of τελειοω, to carry to the end, to complete like love in 1 John 4:18. See James 1:4 for τελειον εργον.
