Paul highlights the global scope of the gospel. Christ became a servant to confirm God’s promises to Israel and to extend mercy to the Gentiles, so that all peoples might glorify God together. The fulfillment of these promises leads to a prayer: that believers would be filled with joy and peace in believing, abounding in hope by the power of the Holy Spirit. True hope is not wishful thinking but confidence rooted in God’s faithfulness. That hope produces durable joy and steady peace, even in the midst of difficulty.
