What wonderful news that God is at work in us to will and to do what pleases him. He who began a good work in us will complete it at the day of Jesus Christ.
God Finishes What He Starts
Sam Storms comments: “Paul prays for believers, “May the God of peace himself sanctify you completely, and may your whole spirit and soul and body be kept blameless at the coming of our Lord Jesus Christ”; Paul then immediately adds, “He who calls you is faithful; he will surely do it” (1 Thessalonians 5:23–24).
As New Testament passages abundantly emphasize, God is faithful to sustain and establish us in our relationship with Jesus; he supplies our every need, all the power, and whatever spiritual resolve is required. As Paul declared, “He who began a good work in you will bring it to completion at the day of Jesus Christ” (Philippians 1:6). Whatever God starts, he finishes!”
