For thou, LORD, hast made me glad through thy work: I will triumph in the works of thy hands.
Psalms 92:4, kjv
Do you believe that your sins are forgiven, and that Christ has made a full atonement for them? Then what a joyful Christian you ought to be! How you should live above the common trials and troubles of the world! Since sin is forgiven, can it matter what happens to you now? Luther said, "Smite, Lord, smite, for my sin is forgiven; if thou hast but forgiven me, smite as hard as thou wilt;" and in a similar spirit you may say, "Send sickness, poverty, losses, crosses, persecution, what thou wilt, thou hast forgiven me, and my soul is glad." Christian, if thou art thus saved, whilst thou art glad, be grateful and loving. Cling to that cross which took thy sin away; serve thou him who served thee. "I beseech you therefore, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service." Let not your zeal evaporate in some little ebullition of song. Show your love in expressive tokens. Love the brethren of him who loved you. If there be a Mephibosheth anywhere who is lame or halt, help him for Jonathan's sake. If there be a poor tried believer, weep with him, and bear his cross for the sake of him who wept for thee and carried thy sins. Since thou art thus forgiven freely for Christ's sake, go and tell to others the joyful news of pardoning mercy. Be not contented with this unspeakable blessing for thyself alone, but publish abroad the story of the cross. Holy gladness and holy boldness will make you a good preacher, and all the world will be a pulpit for you to preach in. Cheerful holiness is the most forcible of sermons, but the Lord must give it you. Seek it this morning before you go into the world. When it is the Lord's work in which we rejoice, we need not be afraid of being too glad.
