Charles Haddon Spurgeon

True members of the church of God wear a distinguishing mark. If you are not different from other people, you have no right in the church of God. If a servant can live with you for years and never discover your love for God, I should think there is none to discover. If you are just the same as those you lived with in your former days, if you have undergone no change, and are like the rest of men, you do not have the distinguishing mark which authenticates your right to be in the church of God.
