I can truly say, that the want of Christ’s love is a greater grief and burden to my soul, than the want of any outward thing in this world. I am in a wanting condition, as to temporals; I want health, and strength, and trading, friends, and money, ‘that answereth all things,’ as Solomon speaks, Eccles. 10:19. And yet all these wants do not so grieve me, and so afflict and trouble me, as the want of Christ, as the want of grace, as the want of the discoveries of that favour that is better than life, Ps. 63:3, 4.
Go and take your fill of earthly pleasures if you will—you will never find your heart satisfied with them. There will always be a voice within, crying, like the leech in Proverbs 30:15, ‘Give! Give!’ There is an empty place there, which nothing but God can fill. You will find, as Solomon did by experience, that earthly pleasures are but a meaningless show—promising contentment but bringing a dissatisfaction of spirit—gold plated caskets, exquisite to look at on the outside, but full of ashes and corruption within.

Thoughts for Young Men, 34.
Sin is what you do when your heart is not satisfied with God. No one sins out of duty. We sin because it holds out some promise of happiness. That promise enslaves us until we believe that God is more to be desired than life itself (Psalm 63:3). Which means that the power of sin’s promise is broken by the power of God’s. All that God promises to be for us in Jesus stands over against what sin promises to be for us without him.
