And let us not be weary in well doing: for in due season we shall reap, if we faint not. – Galatians 6:9

The farmer waits under changing circumstances, and various contingences. At one time he sees the fair prospect of a good crop; the wheat has come up well; he has never seen greener springing from the ground! But perhaps it may be too strong and may need even to be put back. By-and-by, after long showers and cold nights, the wheat looks yellow, and he is half afraid about it; in a while there comes, or he fancies there is blight, or a black smut; nobody knows what may happen! Only a farmer knows how his hopes and fears alternate and fluctuate from time to time. It is too hot, too cold; it is too dry; it is too wet. It is hardly ever quite right, according to his judgment, or rather according to his unbelief. He is full of changes in his mind because the season is full of changes; yet he waits, and he waits with patience. Ah dear friends, when we work for God, how often will this happen! I speak from no inconsiderable experience; there are always changes in the field of Christian labor. At one time we see many conversions, and we bless God that there are so many seals to our testimony. But some of the converts after a while disappoint us; there was the blossom, but it produced no fruit; then there will come a season when many appear to backslide; the love of many waxes cold. Perhaps we have found in the church the black smut of heresy; some deadly heresy creeps in, and the anxious farmer fears there will be no harvest after all. Oh, patience, sir, patience!

So, too, maybe, O evangelical worker, it will be with you. When God shall give you a rich return for all you have done for Him, you will blush to think you ever doubted; you will be ashamed to think you ever grew weary in His service; you shall have your reward. Not tomorrow, so wait; not the next day perhaps, so be patient. You may be full of doubts one day, your joys sink low. It may be rough windy weather with you in your spirit; you may even doubt whether you are the Lord’s, but if you have rested in the name of Jesus; if by the grace of God you are what you are; if He is all your salvation, and all your desire—have patience, have patience, for the reward will surely come in God’s good time! ~ C.H. Spurgeon

…with His stripes we are healed. – Isaiah 53:5

By this Divine remedy our life is healed of its rebellion. This medicine has worked within the heart, and it has also worked outside in the life. Now has the drunk become sober and he hates the cup he used to love. Now has the swearer’s foul mouth been washed and his lips, once so polluted, are like lilies dropping sweet, smelling myrrh. Now has the cruel and unkind one becomes tender, gentle and loving—the false has become true, the proud bends his neck in humility, the idle has become a diligent servant of Christ! The transformation is wonderful and this is the secret, “With His stripes we are healed.”

Yet again, our consciousness assures us that we are healed. We know that we are healed, and we rejoice in the fact— and we are not to be argued out of it. There seems to be a theory, held by some people, to the effect that we cannot tell whether we are saved or not. When we have had a disease in our body, we can tell whether we have been healed or not, and the marks and evidence of the supernatural change that takes place within the spirit are as apparent, as a usual rule, and certainly as positive and sure as the changes worked in the body by healing medicine! We know that we are healed. I am not talking to you of a thing which I do not know personally for myself. When the text says, “We,” my heart says, “I,” and I am longing that everybody here should be able to put his own seal to it and say, “That is true! With His stripes we are healed! With His stripes we are healed! With His stripes we are healed!” ~ C.H. Spurgeon

…and with His stripes we are healed. – Isaiah 53:5

And that He died for all, that they which live should not henceforth live unto themselves, but unto Him which died for them, and rose again. – 2 Corinthians 5:15

(T)hose who have believed in the stripes of Jesus are witnesses to the instant and perfect efficacy of the medicine. We can, many of us, speak from experience, since we can say that “we are healed.” HOW are we healed?

Well, first, our conscience is healed of every smart. God is satisfied with Christ and so are we. If, for Christ’s sake, He has put away sin without dishonor to Himself, then are we, also, perfectly content and full of rejoicing in the Atonement and we need nothing else to keep our conscience quiet.

By these same wounds of Christ our heart is healed of its love of sin. It was once in love with sin, but now it hates all iniquity. If our Redeemer died because of our sin, how can we live any longer therein? All our past thoughts concerning sin are turned upside down or reversed. Sin once gave us pleasure, but now it gives us the utmost pain and we desire to be free from it, and to be perfectly holy—there is no evil that we would harbor in our bosoms. It did seem an amazing thing that we should look to Christ and so find pardon and that at that same moment we should be totally changed in our nature as to our view of sin, yet it did so happen! While sin was on us, we felt as if we had no hope and, therefore, we went on in sin. But when sin was pardoned, then we felt great joy and, consequently, gratitude and love to God. Our cry is, “Death to sin, now that Christ has died for sin!” “If the One died for all, then all died” and, as in Christ we died to sin, how shall we live any longer therein? ~ C.H. Spurgeon
