Sweet Lord, you are meek and merciful." Who would not give himself wholeheartedly to your service, if he began to taste even a little of your fatherly rule? What command, Lord, do you give your servants? "Take my yoke upon you," you say. And what is this yoke of yours like? "My yoke," you say, "is easy and my burden light." Who would not be glad to bear a yoke that does no press hard but caresses? Who would not be glad for a burden that does not weigh heavy but refreshes? And so you were right to add: "And you will find rest for your souls." And what is this yoke of yours that does not weary, but gives rest? It is, of course, that first and greatest commandment: "You shall love the Lord your God with all your heart." What is easier, sweeter, more pleasant, than to love goodness, beauty, and love, the fullness of which you are, O Lord, my God?
