The truth Paul brings requires response, the response of repentance; and repentance is the work of the whole man. Paul’s truth is ‘existential.’ He who rejects it virtually commits suicide both intellectually and morally.
Yet Paul also knows that sin is of such a nature as to make men prefer intellectual and moral suicide to the truth of God in Christ. Repentance means the recognition of bankruptcy. It involves the suppliant’s attitude begging for mercy, for pardon, for life. It means fleeing from the city of destruction and pressing on to the celestial city even when Mr. Worldly Wise Man and all his friends are going in the other direction. It means bearing the offence of the cross. Will any of the wise of the world accept his gospel and repent?
