The True Gospel
Lesson 1: Believing in Jesus' Name

A Christian obedient to the Great Commission is like a seaman sent to rescue the survivors of a shipwreck. As the seaman approaches the scene of the disaster and notices people here and there struggling desperately to stay afloat in the rough waters, he must quickly bring them the right kind of aid. It is futile to shout, "Hold on, for when daylight comes and the sea subsides, all will be well!" These are the words of a liberal preacher. Also worthless is the legalistic advice, "Swim harder!" No, what the seaman must do is to give each victim something he can cling to until he is pulled from the water. So also, what every Christian must do to help the lost is to throw them the lifeline of the gospel. But it must be a sturdy line made of unbreakable truth. Too often today, however, preachers give out a gospel that has the look and feel of a strong cord, but some of the strands are defective. The imperiled soul who grasps such a gospel may find some temporary security and hope, but when he is caught by the merciless waves of death, the line gives way and he sinks without aid or remedy into hell.

The problem is that much preaching today is rooted in man's thinking rather than in God's thinking. Man's thinking is often pragmatic or political, seeking gain for self rather than gain for God's kingdom. Also, man's thinking is often subservient to traditions or theological systems that come disguised as the invention of God when they are really the invention of man. God's thinking can be known only by a thorough, honest examination of God's Word, the Bible. Therefore, if we wish to preach a true gospel, we must know and understand the Biblical answer to the question, What must a man do to be saved?

The best-known summary of the gospel is a verse that most Christians have committed to memory.

John 3:16

On the authority of this and many similar verses, all evangelical Christians agree that to be saved, a man must believe in Jesus. But what does it mean to believe in Him? Consider the following texts:

John 1:12

John 3:18

Acts 2:21

Acts 4:12

Romans 10:13

1 John 5:13

See also Matthew 12:21 and Acts 3:16. These texts clarify what it means to believe in Jesus by affirming that to be saved, a man must believe in His name. No one should imagine that Jesus' name is just a label distinguishing Him from other beings. His name represents everything that He is. What precisely is His name?

Before Pentecost, Jesus was known as Jesus of Nazareth to His enemies, as Master or Rabbi to His disciples. But on Pentecost, the day marking the beginning of the Church Age, Peter announced that

Acts 2:36

Henceforth Jesus was known as the Lord Jesus Christ, Christ Jesus the Lord, or Jesus Christ the Lord. This is the name that the seeker after salvation must believe and confess.

Acts 16:31

The requirement to believe in Jesus' name makes it impossible to be saved through any false Jesus. Many who say that they have faith in Jesus do not have a saving faith. Why? Because they have a wrong idea of Jesus. Perhaps they think He was just a good man. By "faith in Jesus," they mean that everything will go well if we follow His example. Or they think He fully realized the divine potential in all of us, and "by faith in Jesus," they mean that we too can become divine. Besides these false Jesuses, contemporary religion is promoting many others, none of which has power to save.

To be saved, a man must believe in the real Jesus, in the Jesus who is the Lord Jesus Christ. To believe in His name means not only to know His name, but also to believe that His name truly states who He is. It means not only to believe in the One who is called the Lord Jesus Christ, but also to believe that He is the man Jesus and that the man Jesus is Lord and Christ.

The object of saving faith is the flesh-and-blood man known to history as Jesus of Nazareth. In other words, the seeker who looks to Jesus for salvation must think of Him as a real human being. This elementary condition denies any hope of salvation to people seduced by either of two damnable heresies. The first, ancient Gnosticism, teaches that Jesus was a supernatural being who merely pretended to be a man—who was aloof to real pain and suffering even during His crucifixion. To seek salvation in the nonhuman Jesus of Gnosticism is therefore futile. John says,

1 John 4:3

The necessity of putting one's faith in a real, historical man exposes the danger in another heresy as well—modern neo-orthodoxy. This pernicious doctrine alleges that whether or not Jesus was a great man and even whether or not He existed are questions irrelevant to faith; that the value to be found in Christianity depends not upon the man Jesus, but upon the idea of Jesus; and that a man can exploit this idea and the language of religion to create for himself a self-exalting and ennobling religious experience. Those who embrace this heresy mouth praise to Jesus, but think of Him only as a noble fiction. So long as they withhold the love and devotion due the real Jesus, their religion is vain.

The necessity of repentance. On the authority of many texts, we may state dogmatically that repentance is necessary for salvation.

  1. The command to repent is part of the gospel that the church has been commissioned to preach throughout the world. After His resurrection, Jesus told His disciples

Luke 24:47

  2. The need for repentance was central to the very first proclamation of the gospel. On the day of Pentecost, Peter stood up before the assembled multitude and exhorted them,

Acts 2:38

Some assert that this command remained in force only during a brief transitional period between the Mosaic dispensation and the Church Age. But Peter makes it clear that he is speaking

Acts 2:39

  3. The objective of Paul's preaching was to bring men to repentance. On Mars' hill in Athens, Paul told the philosophers that repentance was now incumbent on all the gentiles.

Acts 17:30

Before King Agrippa, Paul testified in defense of his ministry that he

Acts 26:20

  4. Paul specifically states that repentance is the avenue to salvation.

2 Corinthians 7:10

Definition of repentance. Everywhere in Scripture, repentance means simply a turning from sin.

Matthew 9:13

Luke 15:7

Acts 8:22

2 Corinthians 12:21

Thus, the requirement of repentance means that someone desirous of salvation must, with humility and sorrow of heart, acknowledge before God the great blackness of his sin. He must accept God's verdict that he is a sinner deserving of condemnation. He must utter the sinner's prayer, "God be merciful to me a sinner" (Luke 18:13).

Sorrow for sin is no sorrow at all unless it is accompanied by a desire to be righteous instead of sinful. To fulfill the requirements of true repentance, the sinner must therefore want to escape not only the condemnation of sin, but also the power and practice of sin. Whether or not he says so explicitly, he must seek freedom from the innate overmastering desire to do wrong, and he must earnestly wish to cease sinful deeds. To live righteously, apart from sin, means that he must do the will of Jesus, his rightful Lord and Master. Thus, his desire to stop sinning is equivalent to a desire to serve Jesus, even though he may not clearly see the connection between the two desires, and his repentance is equivalent to believing in Jesus as Lord.

Christ is the Greek translation of the Hebrew word "Messiah," which means "the anointed one," implying "the one commissioned and sent by God."

In the Old Testament, the term designates the man whom God would send into the world to put away unrighteousness.

Daniel 9:25-26

The term "cut off" is used frequently in the law of Moses to signify a judicial sentence of banishment or death. The prophecy here clearly implies that the Messiah (that is, Christ) would be unjustly put to death by the rulers of His people. The Messiah must therefore be the same as the suffering servant in Isaiah.

Isaiah 52:13-53:12

From this text we learn that God's hand of punishment for our sin would fall upon Christ, not us. As our sin-bearer, Christ would suffer and die in our place.

We have said that to be saved, a man must believe that Jesus is the Christ, and we find that the Christ of prophecy is the One who would come to save us from our sin. Thus, besides acknowledging he is a sinner, the seeker after salvation must accept Jesus as his Savior. In other words, he must understand and believe that Jesus made a complete payment for sin through His death on the cross, and he must trust in Him alone for salvation.

The necessity of accepting Jesus as Savior was central to the message that Paul carried throughout the Roman world.

1 Corinthians 15:1-4

In this summary of his own evangelistic preaching, Paul affirms that a man is saved by receiving the gospel (the good news) that Jesus died to put away sin.

A common idea today is that complicated presentations of the gospel are detrimental. Better to keep them as simple as possible. Yet when we examine how the apostles preached, we find that their evangelistic messages were full of doctrine beyond what hearers strictly needed to know for salvation. More often than not, they told hearers that Christ rose from the dead (Acts 2:32; 3:15; 4:10; etc.). Both Paul and Peter instructed the sinner that he would stand in judgment before Christ (Acts 10:42; 17:31). Many other doctrines likewise appear in their preaching to unbelievers.

A principle of good preaching is that no amount of Biblical truth is excessive if it is not confusing. And it is not confusing to warn a prospective convert that the Christian life is difficult and demanding. To do so may be poor salesmanship, but witnessing is not like selling a used car. A frank picture of trouble ahead could only scare off someone whose conversion would prove false anyway. It could not hinder the conversion of someone the Holy Spirit is wooing.

It is the Holy Spirit who opens a man's heart and mind to spiritual truth and quickens the desire for salvation. To accomplish His purpose, He takes whatever the witnessing Christian says and fits it to the man's need. Thus, we cannot harm a prospective convert by giving him too much spiritual truth. If we tell him Christ's teachings on the costs of discipleship, for example, the Holy Spirit will grant him only as much understanding as He wishes him to have.

An alternative view of what a man must do to be saved derives from Paul's statement,

Romans 10:9

Some have taken this verse to mean that verbal confession of Jesus as Lord and heart belief in the Resurrection are the two absolutely necessary and sufficient prerequisites for salvation.

In the context, Paul is contrasting the faith of Christians to the unbelief of Jews. The Jewish frame of reference is especially evident in verses 1, 4, and 5 of the same chapter. Jews ask (verse 6), "Who shall ascend into heaven? (that is, to bring Christ down from above)." In other words, they refuse to accept the Incarnation. Moreover, they ask (verse 7), "Who shall descend into the deep? (that is, to bring up Christ again from the dead)." In other words, they also refuse to accept the Resurrection. The Christian, however, accepts the word of faith which Paul preaches—the word affirming that Jesus is the Lord, the Incarnate God, who rose from the dead (verse 8). This word so restructures the inner man that the believer's mouth readily confesses the Incarnation and his heart readily embraces the Resurrection (verse 9).

Yet, given Paul's choice of the Incarnation and Resurrection as two doctrines distinguishing dead Judaism from vital Christianity, we should not suppose that he means to exclude all other doctrines from the compass of saving faith. Will God save a man who believes in the Incarnation and Resurrection but who denies his own sinful condition?

Moreover, we should not suppose that a gospel presentation omitting one of these doctrines cannot be effective. A good soul-winner will certainly inform a prospective convert that Jesus rose from the dead. But will God reject a man who has not heard about the Resurrection but who has asked for salvation through Christ?

We see, therefore, that Paul's intention in Romans 10:9 is not to set forth two formal conditions of salvation.

When we look for a single verse that most succinctly expresses the requirements for salvation, we find Paul's recollection of what he had preached throughout his career.

Acts 20:21
