Faint, but not fainthearted (Spurgeon)

But you are not to do a thing merely when it is a pleasure to you; do it when it is a pain to you. When faint, yet be pursuing; when, instead of your legs carrying you, you have to drag your legs along the ground, yet still pursue the enemy... The work that you felt you could not do will have more acceptance with God than that which you performed in your ordinary strength...

...to stand right alone, like a brazen pillar that cannot be stirred though the whole earth should push against you; there is something in such action that is worthy of the grace of God; and it is true grace alone that helps a man to act thus. Brothers and sisters, do not count the difficulties; count your God as everything, and let the rest go which way they will. The more difficulties there are, the better; and the fewer friends, the better; there shall be the more glory to the grace that helps you through loneliness to stand firm, and to be faithful to your God.
