 So, true reconciliation is brought about by removing those obstacles that stand between us, by removing the basis for the enmity. Does that make sense? It presupposes effectively removing that which is the cause of our alienation, namely our sin and our guilt. Our sin and guilt has to be taken out of the way. That removal, the removal of sin and guilt, is brought about through the substitutionary or vicarious work of Jesus Christ when he was made sin for us that we might become the righteousness of God in him. Christ bore the sin, he took upon himself the guilt of those for whom he died, and he removed all obstacles to peace.
