As the deer pants for the water brooks, so pants my soul for You, O God. -Psalm 42:1

Now the just shall live by faith: but if any man draw back, My soul shall have no pleasure in him. -Hebrews 10:38

Can anybody suggest a reason why the lover of Christ should turn from Him? Polycarp was asked that he should curse Christ, and he replied, “Wherefore should I curse Him?” The assembly in the amphitheatre could give no answer to that; all hell could never give a reply to that. What hath He done, what hath He done that we should leave Him? What can He have done, and what is there that the world can offer that would ever repay us for leaving Him? Could we so false, so traitorous, prove as to turn away from Christ, what should we gain? A little pleasure gone in a moment, like thorns that crackle beneath the pot. What should we lose, my brethren? We should lose the joy of life; we should lose our support in tribulation; we should lose our hope in death; we should lose heaven, to inherit nothing but the blackness of darkness for ever. I cannot conceive a bribe heavy enough to weigh against Him; I cannot imagine an honour bright enough to compare with Him. I cannot conceive a disgrace that can be black enough to compare with the disgrace of deserting Him. The silver mine of Demas is a poor reward for selling His Master. All the wealth of India, could it be poured into one’s lap, were but a mockery of a soul that damned itself by casting away its confidence in Christ. To whom should we go, Master; to whom should we go? Thou hast the words of eternal life. To leave Christ would be the meanest thing of which any could be capable. I suppose the devil himself, with all that he has ever done, has never been able to compass a wickedness that would equal this wickedness, if it were possible of a truly gracious soul deliberately deserting Jesus for the world, for such a soul knows the hollowness of this world’s joys; such a soul knows something of the sweetness of Jesus; such a spirit has been with Him, and has learned of Him, has had the enlightenments of His grace, has learned the faithfulness of His promise and the love of His heart. ~ C.H. Spurgeon
