And I am sure of this, that he who began a good work in you will bring it to completion at the day of Jesus Christ.
Nobody is perfect… yet. Paul is telling the church who supported his ministry that he is grateful for their willingness to help pay his way. He describes it as a “partnership” in his mission, the mission of the gospel. This work was started among them and it will not finish until Jesus comes back, and He is coming back! Praise the Lord! Don’t ever quit, don’t stop, the gospel still needs to go out to all the nations. This will always be our mission until the end, which is really only the beginning of forever!
