Question 65. Since it is by faith alone that we share in Christ and all his benefits, where does this faith come from?

Answer: From the Holy Spirit, (a) who produces faith in our hearts by the preaching of the gospel, and strengthens it by the use of the sacraments. (b)

(Scriptural proofs after the fold.)

a. Ephesians 2:8-9

For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast.

      John 3:5

Jesus answered, “Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God. 

      1 Corinthians 2:10-14

… these things God has revealed to us through the Spirit. For the Spirit searches everything, even the depths of God. For who knows a person’s thoughts except the spirit of that person, which is in him? So also no one comprehends the thoughts of God except the Spirit of God. Now we have received not the spirit of the world, but the Spirit who is from God, that we might understand the things freely given us by God. And we impart this in words not taught by human wisdom but taught by the Spirit, interpreting spiritual truths to those who are spiritual. The natural person does not accept the things of the Spirit of God, for they are folly to him, and he is not able to understand them because they are spiritually discerned. 

      Philippians 1:29

For it has been granted to you that for the sake of Christ you should not only believe in him but also suffer for his sake … .

b. Romans 10:17

So faith comes from hearing, and hearing through the word of Christ.

      1 Peter 1:23-25

since you have been born again, not of perishable seed but of imperishable, through the living and abiding word of God; for “All flesh is like grass and all its glory like the flower of grass. The grass withers, and the flower falls, but the word of the Lord remains forever.” And this word is the good news that was preached to you.

      Matthew 28:19-20

Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age.

      1 Corinthians 10:16

The cup of blessing that we bless, is it not a participation in the blood of Christ? The bread that we break, is it not a participation in the body of Christ?
