A. First, we must from the heart call upon the one true God only, who has revealed Himself in His Word, for all that He has commanded us to pray. Second, we must thoroughly know our need and misery, so that we may humble ourselves before God. Third, we must rest on this firm foundation that, although we do not deserve it, God will certainly hear our prayer for the sake of Christ our Lord, as He has promised us in His Word.

27. Q. What do you understand by the providence of God?
A. God’s providence is His almighty and ever present power, whereby, as with His hand, He still upholds heaven and earth and all creatures, and so governs them that leaf and blade, rain and drought, fruitful and barren years, food and drink, health and sickness, riches and poverty, indeed, all things, come not by chance but by His fatherly hand.
21. Q. What is true faith?
A. True faith is a sure knowledge whereby I accept as true all that God has revealed to us in His Word. At the same time it is a firm confidence that not only to others, but also to me, God has granted forgiveness of sins, everlasting righteousness, and salvation, out of mere grace, only for the sake of Christ’s merits. This faith the Holy Spirit works in my heart by the gospel. The Heidelberg Catechism (1563)
