Our salvation is the work of Christ, and so is our sanctification every day that follows.
Paul wrote to the Colossians, “I rejoice in my sufferings” (1:24). Can you imagine yourself saying that? It’s a difficult claim to make, much less to adhere to day after day. In fact, that would be impossible for us to do on our own.
The apostle was able to have such an attitude only because he drew from Jesus’ strength—and the same is true for us. We can try to live the Christian life by our own efforts, but we won’t succeed. Jesus Himself told the disciples, “The one who remains in Me, and I in him bears much fruit, for apart from Me you can do nothing” (John 15:5).
To live a healthy spiritual life, it’s essential to recognize that power has nothing to do with us; it comes from Christ in us. Our salvation is the work of God, as is every bit of our sanctification throughout the rest of earthly life. Not only does He transform us; He’s also the one who empowers us to obey and serve as we rely on Him. Paul understood how our responsibility and God’s power intersect. In verse 29 of today’s passage, he expressed it this way: “For this purpose I also labor, striving according to His power which works mightily within me.”
