Just as in eternity God acted like Himself and when incarnated in human flesh still continued to be true to His holiness in all His conduct, so does He when He enters the nature of a believing man. This is the method by which He makes the redeemed man holy. He enters a human nature at regeneration as He once entered human nature at the incarnation and acts as becomes God, using that nature as a medium of expression for His moral perfections.
Cicero, the Roman orator, once warned his hearers that they were in danger of making philosophy a substitute for action instead of allowing it to produce action. What is true of philosophy is true also of religion. The faith of Christ was never intended to be an end in itself nor to serve instead of something else. In the minds of some teachers faith stands in lieu of moral conduct and every inquirer after God must take his choice between the two. We are presented with the well-known either/or: either we have faith or we have works, and faith saves while works damn us. Hence the tremendous emphasis on faith and the apologetic, mincing approach to the doctrine of personal holiness in modern evangelism. This error has lowered the moral standards of the church and helped to lead us into the wilderness where we currently find ourselves.
