Salvation is an expansive term. It essentially means "safety." Salvation includes the application of Christ's work from the new birth, through faith and repentance, to Justification, adoption, sanctification, and glorification. Christians share in Christ's benefits because they are united to him through faith and they enjoy communion in all his benefits. We have been saved (Eph. 2:8), we are being saved (2 Cor. 2:15), and we shall be saved (Rom. 5:9). God uses means such as the Word, the sacraments, and prayer to save sinners (WSC 88). We receive Christ by faith as we use his appointed means to foster and to exercise our faith.
Is reading the Bible in private enough to save us? Not ultimately. Like the Bereans, we must receive the preached Word "with all readiness" and we must search the Scriptures daily "to find out whether these things [are] so" (Acts 17:11). Preaching is necessary for salvation because it is the ordinary means through which we hear Christ and are saved by him. This passage explains why preaching is necessary, who should do it, what it proclaims, its opposition, and its purpose. These truths show us why we need preaching as a means of promoting our salvation through union and communion with Christ.
The necessity of preaching of so clearly highlighted by the Apostle Paul in Romans 10, where he wrote:
"How then shall they call on Him in whom they have not believed? And how shall they believe in Him of whom they have not heard? And how shall they hear without a preacher? And how shall they preach unless they are sent? As it is written: 'How beautiful are the feet of those who preach the gospel of peace, who bring glad tidings of good things!' But they have not all obeyed the gospel. For Isaiah says, 'Lord, who has believed our report?' So then faith comes by hearing, and hearing by the word of God" (Rom. 10:14-17).
Preaching is necessary because people need to hear Christ in order to believe in him for salvation. Romans 9-11 answers the question why so many Jews did not receive Christ as their Messiah. In chapter 9, Paul answered that not all Jews came to faith because God did not elect all of them to salvation. Chapter 11 concludes that God preserved an elect remnant of ethnic Jews now, such as Paul, and that God would save many more of them in the future. Chapter 10 explains that unbelieving Jews were accountable for their unbelief. Paul explained that God would save both Jews and Gentiles through preaching. He pressed the necessity of preaching in light of the fact that people need to call upon Christ through faith. Circumcised Jews needed to be circumcised in heart (Jer. 9:25-26; Rom. 2:28-29). Uncircumcised Gentiles "were without Christ, being aliens from the commonwealth of Israel and strangers from the covenants of promise, having no hope and without God in the world" (Eph. 2:12). Only Christ's blood could bring both Jews and Gentiles near to God (v. 13-18). Paul added that it was not enough to hear about Christ. People need to hear Christ's voice. The Greek text of Romans 10:14 says literally, "How shall they believe him whom they have not heard? And how shall they hear [him] without a preacher?" As Christ spoke in Paul (2 Cor. 13:3), and as Christ pleads with sinners through his ambassadors (2 Cor. 5:20), so people hear Christ through preachers in order to believe Christ himself. This does not mean that Christ does not call people through Bible reading and that he does not use the sacraments and prayer as means of salvation. Yet preaching is the ordinary means by which we must learn Christ and hear his voice (Eph. 4:20). How God can save sinners and how he ordinarily chooses to do so are different questions. When we listen to sermons, we should expect to hear Christ in the sermon as he calls us to himself by his Word and Spirit.
Preaching comes through Christ's sent messengers. This implies that preachers are necessary for preaching and that God must equip and send them to preach on Christ's behalf. This point builds upon the previous post, which defined preaching as a public authoritative proclamation of the gospel through Christ's ordained ambassadors. To identify preaching we must identify the preacher properly. We saw that Christ gifts preachers through the Spirit. Christ sends preachers to do their work by calling them to office through the church. He calls men to office through the election of the congregation and the laying on of hands by a group of elders (presbytery, in Greek. Acts 1:23, 6:3-6, 14:23; 1 Tim. 4:14). This former act is election and latter is ordination. The church recognizes the gifts of those whom Christ is sending to preach; it does not convey gifts to them. This reinforces the idea that we must define preaching largely in terms of office. We should seek to hear and receive Christ through the preaching of those preachers whom he has sent.
Preaching is necessary because it brings to us glad tidings from God. Paul cited Isaiah 52:7 to show the blessedness of those who bring "the gospel of peace." "Gospel" means "good news" and proclaiming this good news is inherent to preaching. This means that preaching has a positive aim. It is the "sweet savor of Christ" to God" (2 Cor. 2:15) and God intends preaching to be the "savor of life unto life" to those who believe (v. 16). Preaching should have a positive tone because Christ's person and work are its objects. In preaching, we hear the voice of the Christ who saves.
The positive aim of preaching often meets opposition. Paul cited Isaiah 53:1 to show that preaching does not always bring life. The preached Word becomes a "savor of death" to those who reject Christ (2 Cor. 2:16). It was so to unbelieving Israel in Isaiah's day, it was so to unbelieving Jews in Paul's day, and it remains so to all people who refuse Christ's voice through preaching today. Preaching condemns incidentally. Its aim is to save rather than to condemn. Preaching announces God's love in sending his Son to save those who believe (Jn. 3:16). He did not send him to condemn the world, but to save it (v. 17). Preaching condemns only those who do not believe in the only begotten Son of God (v. 18). People bring their own darkness to bear on the gospel, the nature of which is light (v. 19). Those who love darkness hate light and shun its radiance (v. 20). Yet those who love the truth as it is in Jesus (Eph. 4:21) love the light that he is and brings. The darkness in people's hearts leads them to flee the light, but the darkness of the world cannot overcome the light (Jn. 1:5). God will achieve the end of calling people out of darkness into his marvelous light (1 Pet. 2:9) and he will use preaching as a means of doing so.
Preaching is necessary as the primary means that Christ uses to bring people to salvation because it is his primary means of promoting saving faith. "Faith comes by hearing, and hearing by the word of God" (Rom. 10:17). Some manuscripts read, "the word of Christ," instead of, "the word of God." In either case, Paul teaches us that preaching is the primary means of converting sinners and of building up the saints to salvation because we hear Christ through preaching. Christ must, therefore, be the primary object of preaching. Though preaching is defined largely in terms of office, Christ's work in sending preachers defines preaching in terms of its content as well. Christ commissions preachers, they speak on Christ's behalf, and Christ speaks through them, in order to unfold the unsearchable riches of Christ (Eph. 3:8). Failing to preach Christ in a sermon denies the definition and nature of preaching. Christian sermons must be distinctively Christian. Do we listen to sermons expecting to hear and receive Christ through them?
