Pope Shenouda III
A student, for instance, may study while fasting and have God join him. He studies while God grants him the power to understand and to remember the information learnt in memory. This student says to God: "O Lord, I cannot understand all this by myself. You stay with me and make me understand and I shall thank you for it. I study, O Lord, neither for the sake of knowledge nor for my future, but for You so that all may know that Your children are successful, that they are faithful in all the deeds they undertake, and that the Lord is with them and assists them. Thus people give praise "
