It is then clear, I think, from what has been said, that nonconformity to the world is not the _aim_, but one of the incidents of Christian life. The Christian’s _aim_ is distinctly stated here to be the proving of the will of God—that which is good, acceptable and perfect. Yet nonconformity to the world will develop itself as a _necessary incident_ of Christian living. Being transformed by the renewing of the mind, the outward life will necessarily be transformed also, and will cease to be conformed to the world. The soul which desires that which is good, acceptable, perfect, can no longer find affinity with that which is bad, imperfect, and displeasing to God. The differences are not incidental, they are generic. The Christian and the world belong to different orders; are regulated by different laws. The Christian is, as it were, grafted upon the new stock, and can no more bear the fruit of his old sinful life, than the ingrafted branch can bear its former fruit. Old things have passed away. All things have become new. He is a new creature in Christ Jesus. These differences have not to be marked by finely drawn lines of casuistry. There are indeed points at which the worldly and the Christian life run for a little way parallel. Points where neither party can very well act differently from the other. But for all that, the divergence is wide enough at many other points to leave no doubt. I am speaking now of _true_ Christians, thoroughly renewed in the spirit of their mind; courageous, unflinching, consistent Christians: not of those whifflers and compromisers who call themselves Christians, and who try to trim between God and the world, so as to relinquish no advantages on the side of either. A man cannot live many hours by the rule of Christ without coming into direct issue with the world. And now, as to these points of difference, they are, of course, too numerous to be dealt with in detail. And I can, therefore, only call your attention to one or two classes of them. 1st: On which I need not dwell, is the class of _worldly sins_. Of course the transformed man will not be conformed to the world in these. Not that a Christian never errs, by any means, but that the general current of his life will set in the direction of pleasing God, and away from those things which are plainly contrary to his will.
