Paul writes to the church at Philippi, “I am sure of this, that He who started a good work in you will carry it on to completion until the day of Christ Jesus.” The good work, I believe, to which Paul refers is their partnership with him in grace. These brothers and sisters in Christ partner with Paul to establish and defend the gospel. And God “carries it on to completion.” God has not begun this good work to see it fail.
Paul exhorts, “Just one thing: live your life in a manner worthy of the gospel of Christ. Then, whether I come and see you or am absent, I will hear about you that you are standing firm in one spirit, with one mind, working side by side for the faith of the gospel, not being frightened in any way.” (Philippians 1:27-28)
Paul calls them and us to stand together in “one spirit, with one mind, working side by side for the faith of the gospel” and to do so without fear. He reminds, “If God is for us, who is against us? He did not even spare His own Son, but offered Him up for us all; how will He not also with Him grant us everything? Who can bring an accusation against God’s elect? God is the One who justifies. Who is the one who condemns?” (Romans 8:31-34)
