We are to humble ourselves to this,—that we address ourselves to the performance of the greatest duties, being fully persuaded that we have no strength for the least. This is that which lies so cross to flesh and blood, that our souls must be humbled to it if ever we are brought to it; and yet without this there is no walking with God.
There are great and mighty duties to be performed in our walking with God in a way of gospel obedience: there is cutting off right hands, plucking out right eyes; denying, yea, comparatively, hating father, mother, and all relations ; dying for Christ, laying down our lives for the brethren ; crucifying the flesh, cutting short all earthly desires, keeping the body in subjection, bearing the cross, self-denial,and the like;—which, when they come to be put in practice, will be found to be great and mighty duties.
This is required in the law of grace,—that we undertake and go through with these all our days, with a full assurance and persuasion that we have not strength of ourselves, or in ourselves, to perform the least of them. “We are not sufficient of ourselves,” saith the apostle, 2 Cor. 3:5. We cannot think a good thought. Without Christ we can do nothing, John 15:5.
