Quietness of heart

"But, where contentment of heart springs from grace, the heart is very quick and lively in the service of God. Yea, the more any gracious heart can bring itself to be in a contented disposition, the more fit it is for any service of God. It is very active and lively, not dull, in the service of God. And just as a contented heart is very active and busy in the work of God, so he is very active and busy in sanctifying God’s name in the affliction that befalls him…he whose contentment is of grace is not disquieted and keeps his heart quiet with regard to vexation and trouble, and at the same time is not dull or heavy but very active to sanctify God’s name in the affliction that he is experiencing. For if a man is to be free from discontent and worry it is not enough merely not to murmur but you must be active in sanctifying God’s name in the affliction. Indeed, this will distinguish if from a sturdy resolution not to be troubled. Though you have a sturdy resolution that you will not be troubled, do you make it a matter of conscience to sanctify God’s name in your affliction and is this where your resolution comes from? That is the main thing that brings quietness of heart and helps against discontent in a gracious heart. I say, the desire and care your soul has to sanctify God’s name in an affliction is what quietens the soul, and this is what others lack."
