New City Catechism - Question 30


Q30: What is faith in Jesus Christ?

A:  Faith in Jesus Christ is acknowledging the truth of everything that God has revealed in his Word, trusting in him, and also receiving and resting on him alone for salvation as he is offered to us in the gospel.

Kids’ Answer:

Receiving and resting on him alone for salvation as he is offered to us in the gospel.



Galatians 2:20

"I have been crucified with Christ. It is no longer I who live, but Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me."



1 Corinthians 15:1-6



As we have seen, forgiveness for our sin and eternal life come through faith alone. No number of good works can earn us a right standing before God and salvation. Salvation is by grace alone, through faith alone.


But what is faith? What is the particular faith that saves us from future judgment and results in a right relationship with our holy God?


In various realms of life people talk about faith in all kinds of ways. Faith in their doctor’s expertise. Faith in the faithfulness of their spouse. Faith expressed in all kinds of religious practices. Faith in the goodness of their own works. A faith that, for them, equals spirituality. Faith in the power of faith.


So what is biblical faith? What is faith’s definition and what is faith’s content?


We can learn a lot from the author of Hebrews who defines faith this way: “Now faith is the assurance of things hoped for, the conviction of things not seen.


Faith is assurance. It is taking God at his word in what he has promised. In the Bible God promises a glorious future inheritance for those who have this faith. Biblical faith relies completely on God’s power, ability, and faithfulness to fulfill what he teaches and promises. We can rely on God’s absolute, unfailing promise of our future hope of eternal life in heaven with him. Because God is good and able to fulfill his promises, we have a profound sense of assurance that God will, in fact, keep these promises. It is the inner conviction that what God says is true, even if we can’t see it with our eyes (at least not yet).


When it comes to the faith that saves us, there is a specific content and object of our faith. We don’t have faith in our faith. In order to be saved, God calls us to have faith in the gospel message as presented to us in Scripture.


What is that gospel message? In order to be saved, we must believe that God exists and is he’s perfectly holy and just, that God sent his only divine Son, Jesus, to take on flesh and live a sinless life, that Jesus took the sin and judgment of all who would believe on himself on the cross on which he was crucified, that he died, was buried, and resurrected from the dead. Jesus’ atoning work on the cross is what purchases our forgiveness and our salvation, redeems us from the power and penalty of sin, and reconciles us to God.


Therefore, biblical, saving faith is faith in the person and atoning work of Jesus Christ. It is believing that it is true, that it is offered to you in particular, and that you trust in Jesus as your Savior. It is relying and “resting on him alone for salvation.”


Author Greg Gilbert put it this way. “Putting your faith in Christ means that you utterly renounce any other hope of being counted righteous before God…To put it another way, it means jumping off the edge of the pool and saying, Jesus, if you don’t catch me, I’m done. I’ve no other hope, no other savior. Save me, Jesus, or I die.” (What is the Gospel; Crossway, 2010, pg. 79)


The apostle Paul challenged us, “Examine yourselves, to see whether you are in the faith” (2 Cor. 13:5). It’s a good and important challenge. Take a moment to ask yourself whether you have this kind of saving faith in Christ.




We believe that man was created in the image of God, but fell into sin, and is therefore lost, and that only through regeneration by the Holy Spirit can salvation and spiritual life be obtained.  (Gen. 1:26272:7223:1-6Rom. 3:9-12,235:12,186:23;  Jn. 3:35-7)


We believe that Jesus Christ is true God and true Man, having been conceived of the Holy  Spirit and born of  the Virgin Mary.  He who knew no sin died on the cross a sacrifice for  our sins according to the Scriptures.  Further, He arose bodily from the dead, ascended into  Heaven, where at the right hand of the Majesty on High, He now is our High Priest and Advocate.  (Is. 7:14Mt. 1:18-25;  Lk. 1:26-36;  Col. 2:9;  1 Jn. 5:20;  Mk. 10:45;  Heb. 2:9;  Lk. 24:23-40;  1 Cor. 15;  Acts 1:1-111 Pet. 3:221 Jn. 2:2Heb. 4:167:25)


We believe that the shed blood of Jesus Christ and His resurrection provide the only ground for justification and salvation for all who believe, and only such as receive Jesus by faith are born of the Holy Spirit, become children of God, and are saved for eternity.  (Heb. 9:22;     Mt. 26:281 Pet. 1:18,19Rom. 3:2425Rom. 5:1,  918Jn. 1:123:16Eph. 2:8,9)
