The man who knows his sins is greater than one who raises a dead man by his prayer. He who sighs and grieves within himself for an hour is greater than one who teaches the entire universe. He who follows Christ, alone and contrite, is greater than one who enjoys the favor of crowds in the churches.
Isaac the Syrian
Likewise the Spirit helps us in our weakness. For we do not know what to pray for as we ought, but the Spirit himself intercedes for us with groanings too deep for words.
The English Standard Version
He that serves God for money will serve the Devil for better wages.
