Why Did Christ Die?

Was it because sin is so heinous or because humans need a cosmic flannel graph to illustrate God’s displeasure over sin (I don’t think he is weeping about it)? Machen thinks the former:

The atoning death of Christ, and that alone, has presented sinners as righteous in God’s sight; the Lord Jesus has paid the full penalty of their sins, and clothed them with His perfect righteousness before the judgment seat of God. But Christ has done for Christians even far more than that. He has given to them not only a new and right relation to God, but a new life in God’s presence for evermore. He has saved them from the power as well as from the guilt of sin. The New Testament does not end with the death of Christ; it does not end with the triumphant words of Jesus on the Cross, “It is finished.” The death was followed by the resurrection, and the resurrection like the death was for our sakes. Jesus rose from the dead into a new life of glory and power, and into that life He brings those for whom He died. The Christian, on the basis of Christ’s redeeming work, not only has died unto sin, but also lives unto God. (Christianity and Liberalism)

But what if God can change you apart from the death and resurrection of Christ?

In the midst of this crisis, (that went on for more than a year,) I came across the teaching of Martin Luther and his followers, who, when confronted with the same apparently insoluble problem, issued a ruling that was, essentially, against God. Human nature was hopelessly corrupt, top to bottom and god Himself has no power to alter it. They described the human soul as a dung heap, over which the grace of God falls like a deep covering of snow, that changes nothing of the underlying corruption.

This nauseating and plainly wicked doctrine – essentially nihilistic – so infuriated me that I realized in a flash that it was an insult, not to me in my failings, but to God’s infinite perfection and power. My very fury at this insult made me understand at last what the Church had always held: that it is not my power, but the power of God that will change me into this “perfect” new thing. This promise was true, and it had much more to do with Him than with me.

If God can change us, why would he need to send his son to die on the cross?

But if Machen and Luther are right about the extent of sin and the irredeemable character of fallen humans apart from an alien righteousness imputed to them and received by faith, then what incentives do people have to be good?

We cannot “earn” God’s love but, alas, too often we reject it. And it is up to us to use the gifts God has given to us—including our inherent rationality as well as the Church and the aids to faith and reason it provides—to orient ourselves to the good. Through hard work we can develop our character (habits of virtue or vice that go far toward determining who we are) such that we will recognize and say “yes” to God’s will. The saint does not achieve salvation through mere right conduct, but the saint’s conduct, both spiritual and physical, help him to surrender fully to God and do His will. In doing the right thing for the right reason we orient ourselves toward what is right and thereby recognize and accept God.

. . . Good works help develop within us habits that enable us to distinguish between good and evil; good works make it more likely that we will choose the good, even when it brings with it pain and death. This, I submit, is not some prideful claim to earning one’s own salvation, but rather a recognition of both the dignity and the weakness of the human person. We have within us an impulse toward the good, which we too often ignore. We have written on our hearts a knowledge of God’s will, which we also too often ignore. By both thinking and doing right we can embrace the good, opening ourselves to the grace offered by God—who is beyond our full knowledge but who has created within us a soul capable of recognizing His will.

If we have goodness, or an openness to the good within us, why exactly did Christ have to die?

Somethings don’t develop or change. Christianity doesn’t make humanism Christian.
