Question 35 - Since we are redeemed by grace alone, through faith alone, where does this faith come from?
All the gifts we receive from Christ we receive through the Holy Spirit, including faith itself.
Answer for kids:
From the Holy Spirit.
But when the goodness and loving kindness of God our Savior appeared, he saved us, not because of works done by us in righteousness, but according to his own mercy, by the washing of regeneration and renewal of the Holy Spirit, whom he poured out on us richly through Jesus Christ our Savior.
Commentary (from newcitycatechism.com Web App)
We must realize that Christianity is the easiest religion in the world, because it is the only religion in which God the Father and Christ and the Holy Spirit do everything. God is the Creator; we have nothing to do with our existence, or the existence of other things. We can shape other things, but we cannot change the fact of existence. We do nothing for our salvation because Christ did it all. We do not have to do anything. In every other religion we have to do something . . . but with Christianity we do not do anything; God has done it all: He has created us and He has sent His Son; His Son died and because the Son is infinite, therefore he bears our total guilt. We do not need to bear our guilt, nor do we even have to merit the merit of Christ. He does it all. So in one way it is the easiest religion in the world.
Holy Spirit, you sought us when we could not seek you because we were dead in our trespasses and sins. You are the giver of our faith; none of us would believe apart from your regenerating grace, by which you make hearts of stone into hearts of flesh. Let us put aside all boasting in light of your undeserved mercy. Amen.
