an unglorified saint to do; all things God expects from him; all things in a gospel sense; all things comparatively to other men, and to himself, when he was another man. See, I beseech you, how without a Christ, and thro' a Christ, makes one man differ from another; yea, and from himself, as much as can and cannot; all things and nothing; impotency and omnipotency, "Without me ye can do nothing." "Through Christ I can do all things." If therefore you would make a covenant with Eternity to eternity, study Christ more than ever, labour to "know nothing but Jesus Christ, and Him crucified." And therein these two things, _First_, Labour to get interest in Christ. Interest is the ground of influence; union the fountain or spring of communion; so Christ, "as the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye abide in Me." There you have the truth and the simile of it; no fruit from Christ, without being and abiding in Christ; there is truth: illustrated and proved by the vine and the branch; there the simile, which is prosecuted and enlarged by our Saviour. And, as all communion ariseth from union, so look what the union is, such is the communion; Christ was filled with the fulness of God because united to God; the saints receive of the fulness of Christ, because united to Christ. "I in them, and Thou in Me." Only here is the difference. Christ's union with His Father was personal, infinite, and substantial, and therefore the communications were answerable, "For God gave not the Spirit by measure unto Him." But the saints' union with Christ, being of an inferior nature; their communications also are proportional; yet such as serve poor creatures to all blessed saving purposes. And therefore with Paul, labour to "be found in Christ," that so you may know experimentally the power of His resurrection, and the fellowship of His sufferings. All the power and virtue that are in Jesus Christ, are only for them that are in Him, as the branch in the root, as the members in the body.
