that if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved.
For with the heart one believes unto righteousness, and with the mouth confession is made unto salvation.
For the Scripture says, “Whoever believes on Him will not be put to shame.”
For there is no distinction between Jew and Greek, for the same Lord over all is rich to all who call upon Him.
For “whoever calls on the name of the Lord shall be saved.”
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.
It may be that the reader feels a difficulty in believing. Consider that we cannot believe by an immediate act. We come to faith by degrees. There may be such a thing as faith at first sight, but usually we reach faith by stages: we become interested, we consider, we hear evidence, we are convinced, and so led to believe. Evidence weighed and knowledge obtained lead up to faith.
It is true that faith in Jesus is the gift of God, but he usually bestows it in agreement with the laws of mind. Therefore we are told that “faith comes from hearing, and hearing through the word of Christ” (Rom. 10:17). If you want to believe in Jesus, hear about him, read about him, think about him, know about him, and so you will find faith springing up in your heart.
Hear much concerning Jesus. Souls come by the hundreds to faith in Jesus through a ministry that presents him clearly and constantly. Few remain unbelieving under a preacher whose greatest subject is the crucified Christ. Go to the place of worship to see Jesus, and if you do not even hear the mention of his name, take yourself to another place where he is more thought of and is therefore more likely to be present.
Read much about the Lord Jesus. The Bible is the window through which we can look and see our Lord. Read with devout attention over the story of his sufferings and death, and before long the Lord will make faith secretly enter your soul. The cross of Christ not only rewards faith, but causes faith.
If hearing and reading are not sufficient, then deliberately set your mind to end the matter. Either believe or know the reason why you do not believe. See the matter through to the utmost of your ability. Pray that God will help you to make a thorough investigation and to come to an honest decision one way or the other. Consider who Jesus was, and whether the foundation of his person does not entitle him to confidence. Consider what he did, and whether this also must not be good ground for trust. Consider his death, resurrection, ascension, and eternal life that interceded for sinners, and decide whether this does not entitle him to be trusted. Then cry to him, and see if he does not hear you. If you want to know Jesus, get as near to him as you can by studying his character and appealing to his love.
At one time, I might have needed evidence to make me believe in the Lord Jesus, but now I know him so well, by proving him, that I should need a very great deal of evidence to make me doubt him. It is now more natural for me to trust than to disbelieve. Act after act of trusting turns faith into a habit. Experience then brings to faith strong confirmation.
