In the New Testament, the concept of covenant is often subsumed under other metaphors that describe the relationship between the Lord and his people. The most important of these is the “kingdom of God,” which was the primary theme of Jesus’ teaching and preaching. The new Israel is also called God’s temple (Eph. 2:21; 1 Cor. 3:16–17), Christ’s body (Rom. 12:4; 1 Cor. 10:17; 12:12–27; Eph. 2:16; 4:15–16), and the city of God (Matt. 5:14; Rev. 21–22). The numerous references to God as Father, to believers as brothers, and to the church as a household portray the church in terms of a family. There are, however, many references to the covenant itself. The brief covenant formulary of the Old Testament—I will be their God and they shall be my people—is applied to the church by several New Testament writers (Heb. 11:16; 1 Pet. 2:10; Rev. 21:3).
The prayer force in God’s government is as strong as any other force, and all natural and other forces must give way before the force of prayer. Sun, moon and stars are under God’s control in answer to prayer. Rain, sunshine and drought obey His will. “Fire and hail, snow and fog, stormy wind fulfilling his word.” Disease and health are governed by Him. All, all things in heaven and earth, are absolutely under the control of Him who made heaven and earth, and who governs all things according to His own will. (Adapted from E.M. Bounds, The Necessity of Prayer)
