The Lord’s Prayer “is truly the summary of the whole gospel.”1 “Since the Lord … after handing over the practice of prayer, said elsewhere, ‘Ask and you will receive,’ and since everyone has petitions which are peculiar to his circumstances, the regular and appropriate prayer [the Lord’s Prayer] is said first, as the foundation of further desires.”2
