To one who is in great pain ─ God is the Physician of body and of soul ─ Feels that he would gladly suffer at His wish.
I do not pray that you may be delivered from your pains; but I pray earnestly that God gives you strength and patience to bear them as long as He pleases. Comfort yourself with Him who holds you fastened to the cross. He will loose you when He thinks fit. Happy are those who suffer with Him. Accustom yourself to suffer in that manner, and seek from Him the strength to endure as much, and as long, as He judges necessary for you.
Worldly people do not comprehend these truths. It is not surprising though, since they suffer like what they are and not like Christians. They see sickness as a pain against nature and not as a favor from God. Seeing it only in that light, they find nothing in it but grief and distress. But those who consider sickness as coming from the hand of God, out of His mercy and as the means He uses for their salvation, commonly find sweetness and consolation in it.
I pray that you see that God is often nearer to us and present within us in sickness than in health. Do not rely completely on another physician because He reserves your cure to Himself. Put all your trust in God. You will soon find the effects in your recovery, which we often delay by putting greater faith in medicine than in God. Whatever remedies you use, they will succeed only so far as He permits. When pains come from God, only He can ultimately cure them. He often sends sickness to the body to cure diseases of the soul. Comfort yourself with the Sovereign Physician of both soul and body.
I expect you will say that I am very much at ease, and that I eat and drink at the table of the Lord. You have reason. But think how painful it would be to the greatest criminal in the world to eat at the king’s table and be served by him, yet have no assurance of pardon? I believe he would feel an anxiety that nothing could calm except his trust in the goodness of his sovereign. So I assure you, that whatever pleasures I taste at the table of my King, my sins, ever present before my eyes, as well as the uncertainty of my pardon, torment me. Though I accept that torment as something pleasing to God.
Be satisfied with the condition in which God places you. However happy you may think me, I envy you. Pain and suffering would be a paradise to me, if I could suffer with my God. The greatest pleasures would be hell if I relished them without Him. My only consolation would be to suffer something for His sake.
I must, in a little time, go to God. What comforts me in this life is that I now see Him by faith. I see Him in such a manner that I sometimes say, I believe no more, but I see. I feel what faith teaches us, and, in that assurance and that practice of faith, I live and die with Him.
Stay with God always for He is the only support and comfort for your affliction. I shall beseech Him to be with you. I present my service.
