"There is no better way to be granted the petitions that we hold in our hearts than to put all the strength of our prayer into what is most pleasing to God; for then he will not only grant us what we ask -- our salvation; he will also give us what he sees we need and what would be good for us, even though we did not petition him for it. As David says in one of his psalms [Psalm 145:18]: 'The Lord is near to all who call on him in truth'; therefore, may only those things of the highest value form the subject of all petition; may our prayer be for salvation; for as it says later in the psalm [Psalm 145:19-20]: 'The will of those who fear him will be done, and he will hear their cries, and he will save them. God watches over all who love him.' What David is saying, then, is that God will satisfy all our heart's desires and grant us all we want, even though it has not crossed our minds to petition him for them" (St John of the Cross, Ascent of Mount Carmel, 3, 44, 2).
