Heidelberg Catechism · Lord's Day 45
117. What belongs to a prayer which pleases God and is heard by him?
Answer
First, that we sincerely call upon the one true God only, who has revealed himself in his Word, for all that he has commanded us to pray. Second, that we thoroughly know our need and misery, so that we may humble ourselves before God. Third, that we 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.
