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.
Half-finished things are everywhere — the workout plan, the budget spreadsheet, the promise to call more often. So when Paul says he's "sure of this," it's worth pausing on what exactly he's confident about: not that you'll finish what you started, but that God will finish what He started in you.
That's a different claim than most self-improvement advice makes. It doesn't rest on your consistency. It rests on the character of whoever began the work in the first place — and Paul seems convinced that this particular worker doesn't abandon projects halfway through.
If you're someone who's watched your own follow-through fail more times than it's succeeded, this verse isn't asking you to trust yourself more. It's asking whether there might be Someone else's reliability worth considering instead — one whose track record you haven't actually examined yet.
Curious whether that kind of reliability is real or just a nice idea? It's worth looking closer at the one Paul says is doing the work.
A short video on this is coming soon — for now, read on.
