The reference is exclusively to the relation of the believer to the risen Lord, and expresses a peculiar spiritual connection. Rev. David Smith, the distinguished theologian, defines it as a spiritual way of four connecting links, viz.: (1) Christ for us (see II Cor. 5 31), which is substitution; (2) We in Christ (II Cor. 5:7; Rom. 6:1I), which is justification; (3) Christ in us (Rom. 8:11; II Cor. 13:5; Gal. 2:20), which is sanctification, and (4) We for Christ (II Cor. 5:10), which is consecration. This is the condition of Christ's tree disciple. He stands in the world as representa tive and witness-bearer for Christ It is not merely a question of his own salvation; he must be a shining light to guide others, and must live the Christ-life, under whatever circumstances he may be placed. One who lives the Christ-life and all of whose thoughts, acts, influences and hopes are centered on carrying on the work of Christ, and who is guided by his will, can be said to be truly "in Christ."
