From Safety, Fulness, and Sweet Refreshment in Christ, by Jonathan Edwards
The excellency of Christ is an object adequate to the natural cravings of the soul, and is sufficient to fill the capacity. It is an infinite excellency, such an one as the mind desires, in which it can find no bounds.
Christ requires no money to purchase rest of him, he calls to us to come freely, and for nothing.
When guilt is taken away and sin is mortified, then the foundation of fear, and trouble, and pain is removed, and the soul is left in peace and serenity.
Christ is a refuge in all trouble; there is a foundation for rational support and peace in him, whatever threatens us.
