This Gospel of Jesus Christ which God sets forth in the infallible Scriptures combines Jesus’ own declaration of the present reality of the kingdom of God with the apostles’ account of the person, place, and work of Christ, and how sinful humans benefit from it. The Patristic Rule of Faith, the historic creeds, the Reformation confessions, and the doctrinal bases of later evangelical bodies all witness to the substance of this biblical message.
The heart of the Gospel is that our holy, loving Creator, confronted with human hostility and rebellion, has chosen in his own freedom and faithfulness to become our holy, loving Redeemer and Restorer. The Father has sent the Son to be the Savior of the world(1 John 4:14): it is through his one and only Son that God’s one and only plan of salvation is implemented. So Peter announced: “Salvation is found in no one else, for there is no other name under heaven given to men by which we must be saved” (Acts 4:12). And Christ himself taught: “I am the way, the truth and the life. No one comes to the Father except through me” (John 14:6).
Through the Gospel we learn that we human beings, who were made for fellowship with God, are by nature—that is, “in Adam” (1 Cor. 15:22)—dead in sin, unresponsive to and separated from our Maker. We are constantly twisting his truth, breaking his law, belittling his goals and standards, and offending his holiness by our unholiness, so that we truly are “without hope and without God in the world” (Rom. 1:18-32, 3:9-20; Eph. 2:1-3, 12). Yet God in grace took the initiative to reconcile us to himself through the sinless life and vicarious death of his beloved Son (Eph. 2:4-10; Rom. 3:21-24).
The Father sent the Son to free us from the dominion of sin and Satan, and to make us God’s children and friends. Jesus paid our penalty in our place on his cross, satisfying the retributive demands of divine justice by shedding his blood in sacrifice and so making possible justification for all who trust in him (Rom. 3:25-26). The Bible describes this mighty substitutionary transaction as the achieving of ransom, reconciliation, redemption, propitiation, and conquest of evil powers (Matt. 20:28; 2 Cor. 5:18-21; Rom. 3:23-25; John 12:31; Col. 2:15). It secures for us a restored relationship with God that brings pardon and peace, acceptance and access, and adoption into God’s family (Col. 1:20, 2:13-14; Rom. 5:1-2; Gal. 4:4-7; 1 Pet. 3:18). The faith in God and in Christ to which the Gospel calls us is a trustful outgoing of our hearts to lay hold of these promised and proffered benefits.
This Gospel further proclaims the bodily resurrection, ascension, and enthronement of Jesus as evidence of the efficacy of his once-for-all sacrifice for us, of the reality of his present personal ministry to us, and of the certainty of his future return to glorify us (1 Cor. 15; Heb. 1:1-4, 2:1-18, 4:14-16, 7:1-10:25). In the life of faith as the Gospel presents it, believers are united with their risen Lord, communing with him, and looking to him in repentance and hope for empowering through the Holy Spirit, so that henceforth they may not sin but serve him truly.
God’s justification of those who trust him, according to the Gospel, is a decisive transition, here and now, from a state of condemnation and wrath because of their sins to one of acceptance and favor by virtue of Jesus’ flawless obedience culminating in his voluntary sin-bearing death. God “justifies the wicked” (ungodly: Rom. 4:5) by imputing (reckoning, crediting, counting, accounting) righteousness to them and ceasing to count their sins against them (Rom. 4:1-8). Sinners receive through faith in Christ alone “the gift of righteousness” (Rom. 1:17, 5:17; Phil. 3:9) and thus be come “the righteousness of God” in him who was “made sin” for them (2 Cor. 5:21).
As our sins were reckoned to Christ, so Christ’s righteousness is reckoned to us. This is justification by the imputation of Christ’s righteousness. All we bring to the transaction is our need of it. Our faith in the God who bestows it, the Father, the Son, and the Holy Spirit, is itself the fruit of God’s grace. Faith links us savingly to Jesus, but inasmuch as it involves an acknowledgment that we have no merit of our own, it is confessedly not a meritorious work.
The Gospel assures us that all who have en trusted their lives to Jesus Christ are born-again children of God (John 1:12), indwelt, empowered, and assured of their status and hope by the Holy Spirit (Rom. 7:6, 8:9-17). The moment we truly believe in Christ, the Father declares us righteous in him and begins conforming us to his likeness. Genuine faith acknowledges and depends upon Jesus as Lord and shows itself in growing obedience to the divine commands, though this contributes nothing to the ground of our justification (James 2:14-26; Heb. 6:1-12).
By his sanctifying grace, Christ works within us through faith, renewing our fallen nature and leading us to real maturity, that measure of development which is meant by “the fullness of Christ” (Eph. 4:13). The Gospel calls us to live as obedient servants of Christ and as his emissaries in the world, doing justice, loving mercy, and helping all in need, thus seeking to bear witness to the kingdom of Christ. At death, Christ takes the believer to himself (Phil. 1:21) for unimaginable joy in the ceaseless worship of God (Rev. 22:1-5).
Salvation in its full sense is from the guilt of sin in the past, the power of sin in the present, and the presence of sin in the future. Thus, while in foretaste believers enjoy salvation now, they still await its fullness (Mark 14:61-62; Heb. 9:28). Salvation is a Trinitarian reality, initiated by the Father, implemented by the Son, and applied by the Holy Spirit. It has a global dimension, for God’s plan is to save believers out of every tribe and tongue (Rev. 5:9) to be his church, a new humanity, the people of God, the body and bride of Christ, and the community of the Holy Spirit. All the heirs of final salvation are called here and now to serve their Lord and each other in love, to share in the fellowship of Jesus’ sufferings, and to work together to make Christ known to the whole world.
We learn from the Gospel that, as all have sinned, so all who do not receive Christ will be judged according to their just deserts as measured by God’s holy law, and face eternal retributive punishment.
