Alexander Maclaren (1826-1910) was a Scottish preacher who is considered by many “the supreme example of  the Protestant expository preacher.” In fact Maclaren was so dedicated to preaching God’s Word that would refuse speaking engagements when they interfered with his study of the Bible at the time. Quite a difference from many of the hirelings in the evangelical camp today. In this sermon Maclaren uses Romans 12:9-10 as his text to look at some basic Christian morals and particularly as this relates to the oft-misundestood concept of love. Maclaren is absolutely correct when he says: 

it needs ever to be insisted upon, and never more than in this day of spurious charity and unprincipled toleration, that a healthy hatred of moral evil and of sin, wherever found and however garbed, ought to be the continual accompaniment of all vigorous and manly cleaving to that which is good. Unless we shudderingly recoil from contact with the bad in our own lives, and refuse to christen it with deceptive euphemisms when we meet it in social and civil life, we shall but feebly grasp, and slackly hold, that which is good. Such energy of moral recoil from evil is perfectly consistent with honest love, for it is things, not men, that we are to hate; and it is needful as the completion and guardian of love itself.
