And He said to them, “Go into all the world and preach the gospel to every creature. – Mark 16:15

Oh! how great a work it is to gospelize any man, and to gospelize a poor man. What does it mean? It means, to make him like the gospel. Now, the gospel is holy, just, and true, and loving, and honest, and benevolent, and kind, and gracious. So, then, to gospelize a man is to make a rogue honest, to make a harlot modest, to make a profane man serious, to make a grasping man liberal, to make a covetous man benevolent, to make the drunken man sober, to make the untruthful man truthful, to make the unkind man loving, to make the hater the lover of his species, and, in a word, to gospelize a man is, in his outward character, to bring him into such a condition that he labours to carry out the command of Christ, “Love thy God with all thy heart, and thy neighbour as thyself.” Gospelizing, furthermore, has something to do with an inner principle; gospelizing a man means saving him from hell and making him a heavenly character; it means blotting out his sins, writing a new name upon his heart-the new name of God. It means bringing him to know his election, to put his trust in Christ, to renounce his sins, and his good works too, and to trust solely and wholly upon Jesus Christ as his Redeemer. Oh! what a blessed thing it is to be gospelized! How many of you have been so gospelized? ~ C.H. Spurgeon
