The Theology of the New Testament

This One who atones for sin is fully God and divine. (See The Person of Christ.) He has the authority to forgive sins (Mark 2:7). Various NT occurrences of the word “name” indicate Jesus’ divine status: people prophesy in his name (Matt. 7:22) and are to hope in his name (Matt. 12:21), and salvation comes in his name alone (Acts 4:12). But the OT establishes that human beings are to prophesy only in God’s name, hope only in the Lord, and find salvation only in him; thus, such use of Jesus’ name indicates his divinity.

The Greek translation of the OT (the Septuagint) identifies Yahweh as “the Lord.” In quoting or alluding to OT texts that refer to Yahweh, the NT authors often apply the title “Lord” to Jesus and evidently use it in that strong OT sense (e.g., Acts 2:21; Phil. 2:10–11; Heb. 1:10–12). The title is therefore another clear piece of evidence supporting Christ’s divinity. Jesus is the image of God (Col. 1:15; cf. Heb. 1:3), is in the very form of God, and is equal to God, though he temporarily surrendered some of the privileges of deity by being clothed with humanity so that human beings could be saved (Phil. 2:6–8). Jesus as the Son of God enjoys a unique and eternal relationship with God (cf. Matt. 28:18; John 20:31; Rom. 8:32), and he is worshiped just as the Father is (cf. Revelation 4–5). His majestic stature is memorialized by a meal celebrated in his memory (Mark 14:22–25) and by people being baptized in his name (Acts 2:38; 10:48). The Son of God is the eternal divine Word (Gk. Logos) who has become flesh and has been identified as the man who is God’s Son (John 1:1, 14). Finally, in a number of texts Jesus is specifically called “God” (e.g., John 1:1, 18; 20:28; Rom. 9:5; Titus 2:13; Heb. 1:8; 2 Pet. 1:1). Such texts involve no trace of the heresy of either modalism or tritheism. Rather, such statements contain the raw materials from which the doctrine of the Trinity was rightly formulated. (See The Trinity.)

New Testament theology, then, is Christ-centered and God-focused, for what Christ does on earth brings glory to God (John 17:1; Phil. 2:11). The NT particularly focuses on Jesus’ work on the cross, by which he redeemed and saved his people. The story line in each of the Gospels culminates in and focuses on Jesus’ death and resurrection. Indeed, the narrative of Jesus’ suffering and death consumes a significant amount of space in the Gospels, indicating that the cross and resurrection are the point of the story. In Acts we see the growth of the church and the expansion of the mission, as the apostles and others proclaim the crucified and resurrected Lord. The Epistles explain the significance of Jesus’ work on the cross and his resurrection, so that believers are enabled to grasp the height, depth, breadth, and width of the love of God (Rom. 8:39). The significance of the cross is explained in relation to themes such as new creation, adoption, forgiveness of sins, justification, reconciliation, redemption, sanctification, and propitiation. Woven together, these themes teach that salvation comes from the Lord, and that Jesus as the Christ has redeemed his people from the guilt and bondage of sin.

Bound up with the work of Christ is the work of the Holy Spirit. Jesus promised to send the Spirit to those who are truly his disciples (John 14:16–17, 26; 15:26), and he poured out the Spirit on his people at Pentecost (Acts 2:1–4, 33) after he had been exalted to the right hand of the Father. The Spirit was given to bring glory to Jesus Christ (John 16:14), so that Christ would be magnified as the great Savior and Redeemer. Luke and Acts in particular emphasize that the Spirit is given for ministry, so that the church is empowered to bear witness to Jesus Christ. At the same time, having the Spirit within is the mark of a person belonging to the people of God (Acts 10:44–48; 15:7–9; Rom. 8:9; Gal. 3:1–5). The Spirit also strengthens believers, so that they are enabled to live in a way that is pleasing to God. Transformation into Christlikeness is the Spirit’s work (Rom. 8:2, 4, 13–14; 2 Cor. 3:18; Gal. 5:16, 18).

Because of sin, all humanity stands in need of the salvation that Christ brings. The power of sin is reflected in the biblical story line, for even Israel as the chosen people of the Lord lived under the dominion of sin, showing that the written law of God by its own power cannot deliver human beings from bondage to sin. Paul emphasizes that sin and death are twin powers that rule over all people, so that they stand in need of the redemption Christ brings (see Rom. 1:18–3:20; 5:1–7:25). Sin does not merely constitute failure to keep the law of God, but represents personal rebellion against God’s lordship (1 John 3:4). The essence of sin is idolatry, in which people refuse to give thanks and praise to the one and only God, and worship the creature rather than the Creator (Rom. 1:18–25).

But sin is not the last word, since Jesus Christ came to save sinners, thereby highlighting the mercy and grace of God. The fundamental response demanded by God is faith and repentance (see note on Acts 2:38). The call to faith and repentance is evident in the ministry of John the Baptist, in Jesus’ announcement of the kingdom (Mark 1:15), in the speeches in Acts, in the Pauline letters, and throughout the NT. Those who desire to be part of Jesus’ new community (the church) and part of the kingdom of God (God’s rule in people’s hearts and lives) must forsake false gods, renounce self-worship and evil, and turn to Jesus as Lord and Master. The call to repentance is nothing less than a summons to abandonment of sin and to personal faith, whereby people are called to trust in the saving work of the Lord on their behalf instead of thinking that they can save themselves. All people everywhere have violated God’s will and must look outside of themselves to the saving work of Christ for deliverance from God’s wrath. Indeed, the whole of the NT can be understood as a call to repentance and faith (cf. Hebrews 11). Even those who are already believers are to exert themselves in faith and repentance as long as life lasts, for this is the mark of Christ’s true disciples. The NT writers constantly encourage their readers to persevere in faith until the end, and warn of the dangers of rejecting Jesus as Lord at any stage. True believers testify that salvation is of the Lord, and that Jesus Christ is the One who has delivered them from the coming wrath.

The saving promises of God, then, have begun to be fulfilled in a new community, the church of Jesus Christ. The church is composed of believers in Jesus Christ, both Jews and Gentiles, for the laws in the OT that separated Jews from Gentiles (e.g., circumcision, purity laws, and special festivals and holidays) are no longer in force. The church is God’s new temple, indwelt by the Holy Spirit, and is called to live out the beauty of the gospel by showing the supreme mark of Christ’s disciples: love for one another (John 13:34–35).

The church recognizes, however, that she exists in an interim state. She eagerly awaits the return of Jesus Christ, and the consummation of all of God’s purposes. In the interim, the church is to live out her life in holiness and godliness as the radiant bride of Christ, and to herald the good news of salvation to the ends of the earth, so that others who live in the darkness of sin may be transferred from Satan’s kingdom to the kingdom of the Lord. The church longs for the day when she will behold God face-to-face and worship Jesus Christ forever. The new creation will be a full reality, all things will be new, and the Lord will be praised forever for his love and mercy and grace—for NT theology is ultimately about glorifying and praising God.
