Colossians 4:17

Take heed (blepe). Keep an eye on. Thou hast received in the Lord (parelabe en Kuriwi). Second aorist active indicative of paralambanw, the verb used by Paul of getting his message from the Lord ( 1 Corinthians 15:3 ). Clearly Archippus had a call "in the Lord" as every preacher should have. That thou fulfil it (ina authn plhroi). Present active subjunctive of plhrow, "that thou keep on filling it full." It is a life-time job.
