Jamieson, Fausset and Brown on Colossians 1:25

25. am--Greek, "I was made a minister": resuming Col 1:23, "whereof I Paul was made a minister."

dispensation--the stewardship committed to me to dispense in the house of God, the Church, to the whole family of believers, the goods of my Master (Lu 12:42; 1Co 4:1, 2; 9:17; Ep 3:2).

which is given--Greek, "which was given."

for you--with a view to you, Gentiles (Col 1:27; Ro 15:16).

to fulfil--to bring it fully to all: the end of his stewardship: "fully preached" (Ro 15:19). "The fulness of Christ (Col 1:19), and of the times (Ep 1:10) required him so to do" [Bengel].
