From "The Chill of Love" by Horatius Bonar

Horatius Bonar was a Free Church of Scotland minister, poet and hymn writer during the middle of the 19th Century. This is from his sermon, "The Chill of Love"

"Let us notice some of the things which decrease when sin increases.

1. As iniquity increases, faith decreases. Unbelief overflows like a deluge. One sin lets loose another. Faith withers down; dies out, like a flower in a desert.
2. As iniquity increases, truth decreases. For error is sin, and sin is error; so that truth and sin cannot co-exist. Sin expels truth, both from the heart and from the world; from the individual saint, and from the church at large. Darkness dispossesses light.
3. As iniquity increases, righteousness and holiness decrease. A man cannot be both holy and unholy; the encroachments of sin can leave no room for holiness at all. Inch by inch, iniquity creeps in and creeps along.
4. As iniquity increases, religion decreases. Sin drives religion out of the heart, out of the church, out of the world. With abounding iniquity prayer dies out, and praise, and zeal. The service of God becomes irksome; the form without the power is the first stage of the declension; and the second is the abandonment of both power and form.
5. As iniquity increases, delight in the things of God decrease. Sin soon shuts out the Bible, and takes away all relish or appetite for it, except as a book of poetry or antiquity. Pleasure in sin cannot co-exist with pleasure in the Word of God, or the day of God, or any of the things of God. 

But the special thing of which our Lord predicts is the decrease in love, - love to God, love to Himself, love to one another. The atmosphere of sin is poisonous to everything sacred; but the thing which it first especially acts upon is love. It chokes this immediately."
