To talk and boast of Christ is easy, and to use him for the increase of our carnal security, and boldness in sinning: but to live in the daily use of Christ to those ends of his office, to which he is by us to be made use of, is a matter of greater skill and diligence, than many self-esteeming professors are aware of. What Christ himself hath done, or will do, for our salvation, is not directly the thing that we are now considering of; but what use he requireth us to make of him in the life of faith. He hath told us, that his flesh is meat indeed, and his blood is drink indeed; and that except we eat his flesh and drink his blood, we have no life in us. Here is our use of Christ, expressed by eating and drinking his flesh and blood, which is by faith.[83] The general parts of the work of redemption, Christ hath himself performed for us without asking our consent, or imposing upon us any condition on our parts, without which he would not do that work: as the sun doth illustrate and warm the earth whether it will or not, and as the rain falleth on the grass without asking whether it consent, or will be thankful; so Christ, without our consent or knowledge, did take our nature, and fulfil the law, and satisfy the offended Lawgiver, and merit grace, and conquer Satan, death, and hell, and became the glorified Lord of all: but for the exercise of his graces in us, and our advancement to communion with God, and our living in the strength and joys of faith, he is himself the object of our duty, even of that faith which we must daily and diligently exercise upon him: and thus Christ will profit us no further than we make use of him by faith. It is not a forgotten Christ that objectively comforteth or encourageth the soul; but a Christ believed in, and skilfully and faithfully used to that end. It is objectively (principally) that Christ is called our wisdom, 1 Cor. i. 30. The knowledge of him, and the mysteries of grace in him, is the christian or divine philosophy or wisdom, in opposition to the vain philosophy which the learned heathens boasted of. And therefore Paul determined to know nothing but Christ crucified, that is, to make ostentation of no other knowledge, and to glory in nothing but the cross of Christ, and so to preach Christ as if he knew nothing else but Christ. See 1 Cor. i. 23; ii. 2; Gal. vi. 14. And it is objectively that Christ is said to dwell in our hearts by faith, Eph. iii, 17. Faith keepeth him still upon the heart by continual cogitation, application, and improvement: as a friend is said to dwell in our hearts, whom we continually love and think of.
