“The holiness of Christians is the great means of spreading the gospel. Beyond all other missions I commend the mission of holiness. They preach best for Christ who preach at the fireside, who preach in the shop, whose lives are sermons, who are themselves priests unto God, whose garments are vestments, and whose ordinary meals are sacraments. Give us a holy, consecrated people, and we will win, for these are the omnipotent legions with which the world shall be conquered to Christ. We joy in a holy people because they bring glory to God. Mere professors do not so; inconsistent professors dishonor God, of whom I tell you even weeping that they are the enemies of the cross of Christ. A people walking in truth crown the head of Jesus. They compel even blasphemers to hold their tongues, for when they see these holy men and women, they cannot say anything against the gospel which has produced such characters.
Beloved, if you love your pastor, if you love the Bible, if you love the gospel, if you love Christ, if you love God, be a holy people. You who profess to be saved, be true, be watchful. If you would not grieve us, if you would not dishonor the gospel, if you would not crucify Christ afresh, and put him to an open shame, walk as Christ would have you walk; abhor that which is evil, cleave to that which is good. Be in your speech and in your temper, in your business transactions with your fellow-men, and in your communications in the family circle, men approved of God, such as you will wish to have been when your Lord shall come, for he is at the door, and blessed are those servants who are ready for his coming.”
