Thomas Halyburton, The Great Concern of Salvation (Works, p. 126):
The sinner sees so much needful to be done in order to his relief, that he can think of none in heaven or earth that is able to relieve him. He is, as it were, laid in a grave that has a stone rolled to the door; and many a time is he forced to put the question, Who will roll away the stone? He sees mountains lying in the way, and cannot think of an arm sufficient to lift them. In Christ only can he be satisfied. He it is who is the “mighty one, on whom the Lord has laid help,” Ps. 89:19; one chosen out of the people for that very end, that he might be the strength of such as put their trust in him. He is the Lord Jehovah, in whom there is everlasting strength.
