Therefore, since we are surrounded by so great a cloud of witnesses, let us also lay aside every weight, and sin which clings so closely, and let us run with endurance the race that is set before us, looking to Jesus, the founder and perfecter of our faith, who for the joy that was set before him endured the cross, despising the shame, and is seated at the right hand of the throne of God. Consider him who endured from sinners such hostility against himself, so that you may not grow weary or fainthearted.
Christians have a greater example to animate and encourage them in their Christian course than any or all who have been mentioned before, and that is the Lord Jesus Christ: Looking unto Jesus, the author and finisher of our faith, v. 2. Here observe,
(1.) What our Lord Jesus is to his people: he is the author and finisher of their faith—the beginning, perfecter, and rewarder of it. [1.] He is the author of their faith; not only the object, but the author. He is the great leader and precedent of our faith, he trusted in God; he is the purchaser of the Spirit of faith, the publisher of the rule of faith, the efficient cause of the grace of faith, and in all respects the author of our faith. [2.] He is the finisher of our faith; he is the fulfiller and the fulfilling of all scripture-promises and prophecies; he is the perfecter of the canon of scripture; he is the finisher of grace, and of the work of faith with power in the souls of his people; and he is the judge and the rewarder of their faith; he determines who they are that reach the mark, and from him, and in him, they have the prize.
