Charles H. Spurgeon on Psalms 119:37

Turn away, then quicken, etc. The first request is for the removing the impediments of obedience, the other for the addition of new degrees of grace. These two are fitly joined, for they have a natural influence upon one another; unless we turn away our eyes from vanity, we shall soon contract deadness of heart. Nothing causeth it so much as an inordinate liberty in carnal vanities; when our affections are alive to other things, they are dead to God, therefore the less we let loose our hearts to these things, the more lively and cheerful in the work of obedience. On the other side, the more the rigour of grace is renewed, and the habits of it quickened into actual exercise, the more is sin mortified and subdued. Sin dieth, and our senses are restored to their proper use. Thomas Manton.
