John Chrysostom
This means that he did not undertake the journey casually, as many now travel without purpose or need. Necessary and important matters moved him, though he does not wish to say this plainly, but only hints at it.
He did not say, "I am coming to teach you, to instruct you in the faith, to supply what is lacking." Rather, he says, "that I may impart something," thereby showing that he does not give them his own, but transmits what he himself received.
Here again he speaks humbly: "something." I shall impart, he says, something small and proportionate to my own strength. In what does this small thing consist, which he now intends to transmit?
"It is," says the Apostle, "something that serves for your strengthening." Therefore even standing firm and not wavering depends on grace.

Therefore do not lose heart because Paul called this a "gift" of grace. Out of great gratitude to God, he usually calls even good works a gift of grace, because for them also we need much help from above.
By saying "for your strengthening," he secretly showed that the Romans needed greater correction. What he wishes to say is this: for a long time I have desired and asked God to see you, for no other reason than to strengthen you.
I wished to confirm you and firmly plant you in the fear of God, so that you might never waver. Yet he did not say it exactly so, because he might have grieved the Romans.
He hints at the same thing in other words, and gently, expressing it in the phrase, "for your strengthening." Then, since even this was said very strongly, see how the Apostle softens his words by explanation.
The Romans could have said, "What then? Are we wavering, spinning about, and in need of your word in order to stand firm?"
The Apostle forestalls this objection, saying: Rom 1:12. "That is, that I may be comforted together with you by the faith common to you and me."
