Do not pray that things may be according to your desires, for your desires are not always in keeping with the will of God. It is better to pray as you were taught, saying: "Thy will be done" (Matthew 6:10). Pray in this way about all things, for He always desires what is good and profitable for your soul, whereas you do not always seek it.
