Another fault which characterises the prayers of the pagans and of those who do not know the living and true God is vain repetition. It is as if they pray to a dead God, not a living God, and their false conception of God cannot help showing through in the way they address him.
Does Christ forbid us ever to repeat our prayers, and to ask for the same thing again? Why then did Christ teach persistence in prayer: ‘that men ought always to pray, and not to faint’ (Luke 18:1)? Why did Paul plead three times with the Lord that his thorn in the flesh might be taken away (2 Corinthians 12:8)? And why did Christ himself pray three times that the cup of the cross might pass from him (Matthew 26:39-44)? Evidently we may ask for the same thing more than once. God is often pleased to test our faith by not answering us at first. A child who is not given the definite answer, ‘no’, may ask again in the hope of prevailing. What Christ forbids is repetition that implies that God is less than he is, or that thinks there is merit in repetition, like the Roman Catholic use of the Lord’s Prayer, or prayer to Mary . Such prayer insults God and damages our perception of the divine nature. God does not need to be spoken to as if he is hard of hearing, as if he is slow to understand what we mean, as if sheer repetition can break down his resistance to answering us, or as if repeated asking of the same thing accrues credit in heaven. Our prayers should recognise God for what he is: the God who made us and understands us perfectly, who is of infinite intelligence and can learn nothing from his creatures, who has invited all men to come to him with their requests, and who can easily answer our petitions because nothing is impossible for him.
