Charles Ellicott Commentary Philippians 1:25

"And having this confidence, I know that I shall abide, yea, and abide with you all, for your progress and joy in the faith;" — Philippians 1:25 (ASV)

I know.—The word is not to be pressed too far. It is simply, “I feel certain”; and it is obvious to remark that in Acts 20:25 it is used by St. Paul of a conviction (that he would “see the face” of the Ephesians “no more”) which, so far as we can follow out the history, was not verified. The apostolic inspiration, like the apostolic power of miracle, was a gift relative to the apostolic work, not necessarily extending beyond it.

Abide and continue with you.—The latter verb is in the original a compound of the former, “I shall abide,” and “shall abide side by side with you.” It was for their sakes that it was necessary for him to live. Hence to the simple idea “I shall abide,” it was natural to add at once the phrase “with you,” or “for you,” as explaining the very object of his abiding in the flesh.

For your advancement and joy of faith.—In these words St. Paul’s presence with them is spoken of, first, as in some degree necessary for their spiritual advance; next, as being to them a gift of God for their joy and comfort, even beyond what was actually necessary. (See the next verse.)
