Romans 11:29, "the gifts and the calling of God are irrevocable," shows that God's plan never changes and that there is no Plan B. The Greek word ametameletos means "without repentance," so neither His purpose nor the gifts He gives to advance it can be revoked. The only variable is human free moral agency, yet God also supplies the strength to overcome carnal nature and stay committed to His plan. Luke, an inconspicuous Gentile, illustrates this. As Paul's constant companion through hardship, he was prepared by God to use his gifts of mind and writing. He wrote perhaps nearly a third of the New Testament, bringing clarity for Jew and Gentile alike about Jesus Christ, the perfect Man, and about Paul's hard-to-understand teachings. Possibly Hebrews came from him too. Jason's costly gift of hospitality shows that even seemingly small gifts are part of God's plan to turn the world upside down. Gifts develop under pressure and are used by God in His own time and way, even when believers cannot see the long game. Because the gifts are irrevocable, believers are to submit humbly, keep their focus on the Kingdom of God, and ask how well they are using their gifts for His glory, trusting that nothing can separate them from God's love in Christ.
