Contentment is not by addition but by subtraction: seeking to add a thing will not bring contentment. Instead, subtracting from your desires until you are satisfied only with Christ brings contentment.
Jeremiah BurroughsWhen [the saints] perform actions to God, then the soul says: 'Oh! that I could do what pleases God!' When they come to suffer any cross: 'Oh, that what God does might please me!' I labour to do what pleases God, and I labour that what God does shall please me: here is a Christian indeed, who shall endeavour both these. It is but one side of a Christian to endeavour to do what pleases God; you must as well endeavour to be pleased with what God does, and so you will come to be a complete Christian when you can do both, and that is the first thing in the excellence of this grace of contentment.
Jeremiah BurroughsNow this is a mystery to a carnal heart. They can see no such thing; perhaps they think God loves them when he prospers them and makes them rich, but they think God loves them not when he afflicts them. That is a mystery, but grace instructs men in that mystery, grace enables men to see love in the very frown of God's face, and so come to receive contentment.
