How, then, is it that believers are united to Christ? Is it in incarnation, or resurrection? In resurrection, assuredly. How is this proved? "Except a corn of wheat fall into the ground and die, it abideth _alone_." (John xii. 24.) At this side of death, there could be no union between Christ and His people. It is in the power of a new life that believers are united to Christ. They were dead _in sin_, and He, in perfect grace, came down and (though Himself pure and sinless) was "made sin," "died _unto sin_," put it away, rose triumphant over it and all pertaining to it, and, in resurrection, became the Head of a new race. Adam was the head of the old creation, which fell with him. Christ, by dying, put Himself under the full weight of His people's condition, and having perfectly met all that was against them, rose victorious over all, and carried them with Him into the new creation, of which He is the glorious Head and Centre. Hence, we read, "He that is joined unto the Lord is one spirit." (1 Cor. vi. 17.) "But God, who is rich in mercy, for His great love wherewith He loved us, even when were _dead in sins_, hath quickened us _together with Christ_, (by grace ye are saved;) and hath raised us up together, and made us sit together in heavenly places in Christ Jesus." (Eph. ii. 4-6.) "For we are members of His body, of His flesh, and of His bones." (Eph. v. 30.) "And you, being _dead in your sins_ and the uncircumcision of your flesh, _hath He quickened together with Him_, having forgiven you all trespasses." (Col. ii. 13.) Passages might be multiplied, but the above are amply sufficient to prove that it was not in incarnation, but in death, that Christ took a position in which His people could be "quickened together with Him." Does this seem unimportant to the reader? Let him examine it in the light of Scripture. Let him weigh all the consequences. Let him view it in its bearing upon Christ's Person, upon His life, upon His death, upon our condition by nature in the old creation, and our place through mercy in the new. Let him consider it thus, and I feel persuaded he will no longer regard it as a light matter. Of one thing, at least, he may rest assured, that the writer of these pages would not pen a single line to prove this point did he not consider it to be fraught with the most momentous results. The whole of divine revelation so hangs together--is so adjusted by the hand of the Holy Ghost--is so consistent in all its parts, that if one truth be disturbed, the entire arch is injured. This consideration should suffice to produce, in the mind of every Christian, a holy caution, lest, by some rude touch, he mar the beauteous superstructure. Every stone must be left in its divinely appointed place; and, unquestionably, the truth as to Christ's Person is the key-stone of the arch.
