Scripture questions are of several uses, hold forth several senses; here it seems to be an approbation of the action spoken of. Who is this? What one is this, that so carefully engageth his heart? This is not ordinary among men, nor of an ordinary degree in man; few move, fewer engage themselves to move towards God. This approbation hath, 1. Its foundation in a duty: I approve this engaging, and the man because he engageth. 2. Its direction from the subject, heart. The engagement of the outward man may have wrong principles: that it may be right, let the heart, soul, inward parts, all that is within us be engaged to bless His holy name. 3. Its limitation from the object, to approach unto me: to engage the heart to sin, to the creature, to vanity, is neither commendable, nor approvable; but to close with God, to come to, stay with, and act for Him, this is that which the prophet, and God in the mouth of the prophet ever approves. And this brings us to, II.--_The propounding of the point, and that in these words._ God observes with the eye of approbation, such as engage and tie themselves to Him; He looks with an approving eye upon this carefulness: for such an engagement of soul is, 1. Needful. 2. Helpful; needful for the heart, helpful to our graces. The needfulness is evident. The heart is slow and subtile, backward and deceitful; except it be drawn with the cords of such an engagement, it puts slowly forward; and when thus drawn, it will fall quickly off. Days of desolation beget resolves, times of terror produce engagements, which the heart (the storm past) will wilily and wickedly seek to evade. David suspected this cozenage in himself, when he cries out, Oh! I have many good thoughts, but a naughty heart; many holy purposes, but a deceitful spirit: thou hast cause, as a Creator, not to believe the tender of my obedience, nor as a just God, the promise of submission; but I call to Thy mercy to give assistance. "Be surety for Thy servant for good:" for the performance of all good I promise. And Hezekiah in his sickness was not without fear of this deceitfulness: "Oh Lord, I am oppressed, undertake for me;" I shall never keep my word, that word which my lips have spoken; and I have none dare pass his word for me: "do thou, O Lord, undertake for me."
