Rom 15:29

“Wherefore instruction, which reveals hidden things, is called illumination, as it is the teacher only who uncovers the lid of the ark, contrary to what the poets say, that "Zeus stops up the jar of good things, but opens that of evil." "For I know," says the apostle, "that when I come to you, I shall come in the fulness of the blessing of Christ;" designating the spiritual gift, and the gnostic communication, which being present he desires to impart to them present as "the fulness of Christ, according to the revelation of the mystery sealed in the ages of eternity, but now manifested by the prophetic Scriptures, according to the command of the eternal God, made known to all the nations, in order to the obedience of faith," that is, those of the nations who believe that it is. But only to a few of them is shown what those things are which are contained in the mystery.”

“"And I am sure that, when I come unto you, I shall come in the fulness of the blessing of the Gospel of Christ." What is the force of, "In the fulness of the blessing? Either he speaks of alms (Gr. money), or generally of good deeds. For blessing is a name he very commonly gives to alms. As when he says, "As a blessing and not as covetousness." (2 Cor. ix. 5.) And it was customary of old for the thing to be so called. But as he has here added "of the Gospel," on this ground we assert that he speaks not of money only, but of all other things. As if he had said, I know that when I come I shall find you with the honor and freshness of all good deeds about you, and worthy of countless praises in the Gospel. And this is a very striking mode of advice, I mean this way of forestalling their attention by encomiums. For when he entreats them in the way of advice, this is the mode of setting them right that he adopts.”

“That is, I will see you well-skilled in all the blessings of the Gospel. For by the full blessing of the Gospel he means all the blessings worthy of blessing, that is, of praise according to the Gospel. But you can also understand by "blessing" almsgiving, so that the meaning would be: I will find you perfect in almsgiving and love for mankind. He says this in advance so that, being put to shame by the praises, they would strive to show themselves as such.”

“Then when he says, but I know, he foretells the fruit of his visit, saying: but I know, namely, from my confidence in God's grace, that when I come to you, I shall come in the abundance of the blessing of Christ, i.e., Christ will give his blessing more abundantly to you in my coming, about which it says in a psalm: they shall go from strength to strength (Ps 84:7), and which Laban said to Jacob: I have learned that God blessed me because of you (Gen 32:7).”
