"And when He has come, He will convict the world of sin. . . ." John 16:8 (R.V.)
Very few of us know anything about conviction of sin; we know the experience of being disturbed because of having done wrong things; but conviction of sin by the Holy Ghost blots out every relationship on earth and leaves one relationship only - "Against Thee, Thee only, have I sinned!" When a man is convicted of sin in this way, he knows with every power of his conscience that God dare not forgive him; if God did forgive him, the man would have a stronger sense of justice than God. God does forgive, but it cost the rending of His heart in the Death of Christ to enable Him to do so. The great miracle of the grace of God is that He forgives sin, and it is the death of Jesus Christ alone that enables the Divine nature to for give and to remain true to itself in doing so. It is shallow nonsense to say that God forgives us because He is love. When we have been convicted of sin we will never say this again. The love of God means Calvary, and nothing less; the love of God is spelt on the Cross and nowhere else. The only ground on which God can forgive me is through the Cross of my Lord. There, His conscience is satisfied.
Forgiveness means not merely that I am saved from hell and made right for heaven (no man would accept forgiveness on such a level); forgiveness means that I am forgiven into a recreated relationship, into identification with God in Christ. The miracle of Redemption is that God turns me, the unholy one, into the standard of Himself, the Holy One, by putting into me a new disposition, the disposition of Jesus Christ.
