Dr. Wayne Grudem on What Does It Means to Become a Christian?

[Adapted from Chapter 13 in Wayne Grudem. Christian Beliefs: Twenty Basics Every Christian Should Know (Kindle Locations 1299-1313). Grand Rapids: Zondervan. Kindle Edition]

Paul sets forth an order in which the blessings of salvation come to Christians when he writes in Romans 8:30: “And those whom he predestined he also called, and those whom he called he also justified, and those whom he justified he also glorified.”

Effective Calling

The calling Paul refers to in Romans 8:30 is not the type of “calling” that people sometimes refer to when giving the reason they chose one job over another or chose to become a member of a certain church. Instead, this calling is related to those who were “predestined” and who became “justified.” That is, it is a calling that came specifically to all who are believers in Jesus.

This kind of calling is a summons from the king of the universe; it is a summons that can’t be denied, and it brings about the desired response in people’s hearts. This calling is an act of God the Father, speaking through the human proclamation of the gospel, in which he summons people to himself in such a way that they respond in saving faith. Because it comes from God and always results in saving faith, it is sometimes referred to as effective calling.

When God calls people in this powerful way, he calls them “out of darkness into his marvelous light” (1 Peter 2:9); he calls them “into the fellowship of his Son” (1 Cor. 1:9; cf. Acts 2:39) and “into his own kingdom and glory” (1 Thess. 2:12; cf. 1 Peter 5:10; 2 Peter 1:3). People who have been called by God “belong to Jesus Christ” (Rom. 1:6). They are called to “be saints” (Rom. 1:7; 1 Cor. 1:2) and have come into a realm of peace (1 Cor. 7:15; Col. 3:15), freedom (Gal. 5:13), hope (Eph. 1:18; 4:4), holiness (1 Thess. 4:7), patient endurance of suffering (1 Peter 2:20 – 21; 3:9), and eternal life (1 Tim. 6:12).

 General Calling and the Gospel Call

But there is a broader sense of “calling” that refers to any preaching of the gospel to anyone, whether they respond or not. In distinction from effective calling, which always brings response, we can talk about the “gospel call” in general, which goes forth to all people, and which is sometimes referred to as external calling or general calling.

The gospel call goes forth through the human preaching of the gospel. Paul makes this clear in 2 Thessalonians 2:14, when he writes to believers that their calling from God came through “our gospel” — that is, the gospel that Paul and others preached to them. That is why it is important that we boldly proclaim the gospel message, trusting that God will, through his effective call, do what he did with Lydia in Acts 16:14: “The Lord opened her heart to pay attention to what was said by Paul.”

Not all gospel calls are effective. The job of believers is to explain the gospel message; it is God’s job to make that message or call effective.

 Elements of the Gospel Call

There are three key elements that should be a part of every gospel call: an explanation of the facts concerning salvation; an invitation to respond to Christ personally in repentance and faith; and a promise of forgiveness and eternal life.

The facts concerning salvation are basically these:

(1) All people have sinned (Rom. 3:23).

(2) The penalty for our sin is death (Rom. 6:23).

(3) Jesus Christ died to pay the penalty for our sins (Rom. 5:8).

But simply stating these facts isn’t enough. There must be an invitation to repent and believe this good news personally. One such invitation, originally spoken by Jesus many years ago and found in Matthew 11:28 – 30, should still be heard as if Jesus were speaking it to you today: “Come to me, all who labor and are heavy laden, and I will give you rest. Take my yoke upon you, and learn from me, for I am gentle and lowly in heart, and you will find rest for your souls. For my yoke is easy and my burden is light.”

To those who respond in faith to the gospel call, God promises that their sins will be forgiven and that they will experience eternal life with God himself. “For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life” (John 3:16). As Jesus said in John 6:37, “Whoever comes to me I will never cast out.”

How the Call Is Received

After the invitation to respond to the gospel is given, God must bring about a change in an individual’s heart before he or she is able to respond in faith. That change, a secret act of God in which he imparts new spiritual life to us, is sometimes called regeneration. We play no role in this regeneration; it is completely an act of God.

This change of heart is described in Ezekiel 36:26: “And I will give you a new heart, and a new spirit I will put within you. And I will remove the heart of stone from your flesh and give you a heart of flesh.”

This instantaneous event changes everything. Once it happens, recipients are, in the words of 2 Corinthians 5:17, “a new creation. The old has passed away … the new has come.” This change, although not always immediately realized, results in a transformed heart that leads to a transformed character that produces a transformed life. All areas of life are changed. A regenerated individual should expect a new love for God and his people (Matt. 22:37 – 40), a heartfelt obedience to his commands (John 14:15), and the Christ-like character traits Paul calls the fruit of the Spirit (Gal. 5:22 – 23).

How the Call Is Responded To

Once God has summoned through an effective call and changed a person’s heart through regeneration, the necessary response is repentance and faith. But since the gospel call is a personal call, it requires a personal response. This willing, personal, individual response to the gospel call, in which a person sincerely repents of his sins and places his trust in Christ for salvation, is called conversion.

Simply knowing and affirming the facts of salvation as stated above in the gospel call is not enough. True saving faith, while it includes knowledge (knowing the facts of salvation) and approval (agreeing that the facts are true), also requires trust. Therefore, one who has true saving faith has moved from investigating Jesus’ claims to believing that these claims are true and from believing these claims are true to trusting in Jesus for forgiveness of sins and eternal life with God. If I have true saving faith, I no longer simply believe facts about Jesus; instead, I personally trust Jesus to save me. The Bible uses strong language to describe this personal trust: we do not just have to “believe Jesus” (that is, believe that what he says is truthful), but we have to “believe in him” (that is, put personal trust in him and depend on him): “For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life” (John 3:16).

This trust involves two aspects: repentance and faith.

Paul preached a gospel “of repentance toward God and of faith in our Lord Jesus Christ” (Acts 20:21). The author of Hebrews says that the first two elements of foundational Christian teaching are “repentance from dead works” and “faith toward God” (Heb. 6:1). Repentance means a conscious decision to turn away from your sins, and faith means turning to Christ to forgive those sins. This kind of faith is admitting that you can’t save yourself and at the same time believing that Christ can. Repentance and faith are really two sides of the same coin. For when I genuinely renounce and forsake my sin, I then turn in faith to Christ, trusting in him alone for my salvation. And this initial repentance and faith provides a pattern for ongoing heart attitudes of repentance and faith that continue for the rest of a Christian’s life. As Paul writes in Colossians 2:6, “As you received Christ Jesus the Lord, so walk in him.”

Questions for Review and Application

1. How does someone become a Christian?

2. Can you explain what it means to truly believe in Jesus? What does it mean to truly repent of sins?

3. In what ways can Christians give evidence of their belief in Jesus?
