“Being confident of this very thing, that He who has begun a good work in you will complete it until the day of Jesus Christ.” – Philippians 1:6

A Promise We Can Trust

The Apostle Paul didn’t waver when he penned these words (Holy Spirit inspired). He wasn’t guessing or hoping—he was certain. When God begins a good work in a believer, He will finish it. This isn’t wishful thinking; it’s a divine guarantee tied to a specific moment: “the day of Jesus Christ.” So, what does that mean for us today?

The Day of Christ: Our Blessed Hope

Paul uses a unique phrase here—“the day of Christ”—found only in his letters (e.g., Philippians 1:6, 1 Corinthians 1:8). Unlike the “day of the Lord,” a time of judgment described in verses like Joel 2:31 (“The sun shall be turned into darkness… before the great and awesome day of the Lord”), the “day of Christ” is different. It’s the moment of joy and resurrection for the Church: the Rapture. Paul paints this picture in 1 Thessalonians 4:16-17—when Christ returns in the air, the dead in Christ rise will rise first, and then the living believers are caught up to meet Him. In an instant, when that trump sounds we will be changed in the twinkling of the eye 1 Corinthians 15:51-52. It’s the fulfillment of the Church Age “until the fullness of the Gentiles has come in” (Romans 11:25), when His work of gathering Gentiles into the body of Christ is complete.

This isn’t about wrath—God spares us from that (1 Thessalonians 5:9)—but about our resurrection and reunion with our Savior.

God’s Faithfulness at Work

Paul wrote this promise to the Philippians (and to us), commending their “fellowship in the Gospel from the first day until now” (Philippians 1:5). Imagine that “first day”—Paul arriving in Philippi, sharing the gospel of grace with pagan Gentiles who’d never heard it before. Their faith took root not by their own power, but because God started something in them. And He wasn’t about to abandon it. The same is true for you. The moment you trusted in Christ’s finished work—His death, burial, and resurrection that paid for your sins (1 Corinthians 15:1-4)—God transformed you (2 Corinthians 5:17). Maybe you’ve doubted along the way, wondering if you’ll make it. Here’s the good news: it’s not up to you, God alone saves. He’s faithful to finish what He started.

A Future Secured

In a world full of uncertainty, we don’t have to wonder about our future. Our salvation is secure, not because of our strength, but because of His promise. The “day of Christ” is coming—a day when every believer will see God’s work in them completed. So, take heart. If you’re feeling weary, trust that He’s still at work. If you’re strong, praise Him for carrying you this far. Either way, keep looking up—He’s coming soon!

Living in Confidence Today

Are you resting in this promise? Thank God today for His faithfulness. Let it sink in: the One who began a good work in you isn’t done yet. He’s shaping you, step by step, for that glorious day—“the day of Jesus Christ”.

Be confident, be encouraged—and keep your eyes on Christ!
