People are disturbed and troubled by the real Gospel: under the false gospel they can sleep unto destruction. Bring out the Sword: it is meant to wound; let it exercise its salutary sharpness. The Gospel has two edges so that none may play with it.

When they think to run their fingers along the back of it, they will find themselves cut to the bone. Whether we regard its threats or promises it cuts at sin. Let us therefore know that the power of the Church does not lie anywhere but in the Word as Jesus Himself speaks it.

Charles Spurgeon
