Andrew Murray said, “There are two classes of Christians: soul winners, and backsliders.” In my estimation, there are two great sins a Christian can commit: the greatest is to fail to love the Lord Jesus. The second greatest is not adultery or drunkenness, but it is the sin of silence—to refuse to share the gospel of Jesus Christ.

Suppose you knew the cure for cancer. Would you not tell it? Suppose you were on an island where people were starving to death, and you knew where there was a vast hoard of food. Would you not share what you knew?

Ours is the greatest mission, the greatest message, the greatest Master the world knows anything about. Our mission is the great commission. Our message is the saving gospel of our Lord and Savior, and our master, Jesus Christ Himself, has told us we must take the gospel to every creature on earth. Yet many Christians are sinning against this command. They're committing what I call “the sin of silence.” If you’re not a witness, you're not right with God, I don't care what else you may do.
