I must add also, that Christ himself, who is said to be our life in the verse following my text, is at present hidden from us; he dwells in the unseen world, and the heavens must receive him till the restitution of all things; Acts iii. 21. Christ Jesus is the bread from heaven; John vi. 32, 33. by which the believer is nourished; he is the hidden manna, the divine food of souls: It is upon him the christian lives daily and hourly; it is upon the blood of the Lamb, which is carried up to the mercy-seat, that the believer lives for pardon and peace with God: It is upon the righteousness of his Lord and Head, that he lives for his everlasting acceptance before the throne; it is upon the grace and strength of Christ, that he rests and depends all the day, when he is called forth to encounter the boldest temptations, to fulfil the most difficult duties, or to sustain the heaviest strokes of a painful providence. “_Surely_, saith the saint, _in the Lord alone have I righteousness and strength_; Is. xlv. 24. In the Lord my Saviour, whom the world sees not; but I see him by the eye of faith.” I shall enlarge farther on this subject under the second doctrine. Thus, whether we consider the spiritual acts and exercises of this christian life, or the springs and principles of it, still we shall find it has just reason to be called a secret, or a hidden life. Before I proceed, I shall lay down these two cautions: 1st Caution. Though it is a hidden life, yet I entreat my christian friends, that they would not suffer it to be such a secret, as to be unknown to themselves. God has ordained it to be hidden, not that it might always be unknown to you, but that you might search after it with diligence; and that when you find yourselves possessed of it, you might rejoice in the evidences of your life and his love. Be not satisfied then, O ye professors of the gospel! until you have searched and found this divine life within you. What a poor life must that christian live, who goes from day to day, and from year to year, and still complains, I know not whether I am alive or no!
