death, a perfect obedience that completely met and fully satisfied the demand of the very highest, the divine ideal. 3. _The Resurrection of Christ_.--If the Incarnation naturally issues in the sacrifice unto death, that again is crowned and sealed by Christ's risen life. The Resurrection is the vindication and completion of the Redeemer's work. He who was born of the seed of David according to the flesh was declared to be the Son of God by the Resurrection. It was the certainty that He had risen that gave to His death, in the apostles' eyes, its sacrificial value. This was the ground of St. Paul's conviction that the old order had passed away, and that a new order had been established. 'If Christ be not risen ye are yet in your sins.' In virtue of His ascended life Christ becomes the indwelling presence and living power within the regenerate man. It is in no external way that the Redeemer exerts His influence. He is the principle of life working within the soul. The key {168} to the new state is to be found in the mystical union of the Christian with the risen Lord. The twofold act of death and resurrection has its analogy in the experience of every redeemed man. Within the secret sanctuary of the human soul that has passed from death to life, the history of the Redeemer is re-enacted. In the several passages which refer to this subject the idea is that the changed life is based upon an ethical dying and rising again with Christ.[4] The Christ within the heart is the vital principle and dynamic energy by which the believer lives and triumphs over every obstacle--the world, sin, sorrow, and death itself. 'I live, yet not I, but Christ liveth in me.'[5] All that makes life, 'life indeed'--an exalted, harmonious, and joyous existence--is derived from union with the living Lord, who has come to be what He is for man by the earthly experiences through which He has passed. Thus by His Incarnation, Death, and Resurrection He is at once the source and goal, the spring and ideal of the new life. 'Yea, thro' life, death, sorrow, and through sinning, He shall suffice me for He hath sufficed; Christ is the end, for Christ was the beginning; Christ the beginning, for the end is Christ.'[6]
