The main office of the hand is to take hold of and grasp an object. The human hand is the master-piece of anatomy, the fingers and the strong opposing thumb being expressly constructed by their Divine Artificer to seize and retain objects; and therefore every muscle, artery, vein and nerve conspire together to fulfil this destined office. Is there not in the office of faith something analogous to and corresponding with this? What says the Lord? "Let him take hold of my strength that he may make peace with me, and he shall make peace with me."
There is a taking hold, then, of God's strength. Is not this by faith? Is there any other grace of the Spirit which takes hold of the Lord, as Jacob took hold of the wrestling angel, or as sinking Peter laid hold of the hand of Jesus? "Lay hold on eternal life" is Paul's charge to Timothy. But how is eternal life, and especially Jesus "the Life," laid hold of, except by faith? "He that believeth on Me," says Jesus "hath everlasting life." He has it by laying hold of it.
So we read also of "fleeing for refuge to lay hold upon the hope set before us" (Heb. 6:18) As the manslayer fled for refuge to the appointed city, and when his hand grasped the gates was safe, so guilty sinners flee for refuge to the Lord Jesus, and by faith lay hold upon the hope set before them in the gospel of the grace of God.
