Have we, at any time in our own experience, failed of any thing all our life long hitherto? have we wanted any thing? Our want arises because we will not admit, we will not receive, or we long after other things, which God is not pleased we should have.
There is in God an all-sufficiency of grace and mercy to pardon us; there is an all-sufficiency of spiritual strength to support us and carry us through all our difficulties; there is an all-sufficiency of goodness and beauty to satisfy us; and there is an all-sufficiency of power and glory to reward us.
from a sermon entitled The Everlasting Covenant, The Believer’s Support Under Distress, volume 9 of Works, page 430
