True godliness lies very much in desires. As we are not what we shall be, so also we are not what we would be. The desires of gracious men after holiness are intense – they cause a wear of heart, a straining of the mind, till it feels ready to snap with the heavenly pull. A high value of the Lord’s commandment leads to a pressing desire to know and to do it, and this so weighs upon the soul that it is ready to break in pieces under the crush of its own longings. What a blessing it is when all our desires are after the things of God. We may well long for such longings.
C.H. Spurgeon
