"But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ" (Ephesians 2:13)
The cause of all our human miseries is a radical moral dislocation, an upset in our relation to God and to each other.
For whatever else the Fall of man may have been, it was most certainly a sharp change in man's relation to his Creator. He adopted toward God an altered attitude, and by so doing destroyed the proper Creator-creature relation in which, unknown to him, his true happiness lay.
Essentially salvation is the restoration of a right relation between man and his Creator, a bringing back to normal of the Creator-creature relation.
A satisfactory spiritual life will begin with a complete change in relation between God and the sinner; not a judicial change merely, but a conscious and experienced change affecting the sinner's whole nature.
The atonement in Jesus' blood makes such a change judicially possible and the working of the Holy Spirit makes it emotionally satisfying. The story of the prodigal son perfectly illustrates this later phase.
He had brought a world of trouble upon himself by forsaking the position which he had properly held as son of his father. At bottom his restoration was nothing more than a reestablishing of the father-son relation which had existed from his birth and had been altered temporarily by his act of sinful rebellion. This story overlooks the legal aspects of redemption, but it makes beautifully clear the experiential aspects of salvation.
