Now 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.
