True or right fear is discovered by three things:– 1. By its rise; it is caused by saving convictions for sin. 2. It driveth the soul to lay fast hold of Christ for salvation. 3. It begetteth and continueth in the soul a great reverence of God, his Word, and ways, keeping it tender, and making it afraid to turn from them, to the right hand or to the left, to anything that may dishonour God, break its peace, grieve the Spirit, or cause the enemy to speak reproachfully.
The Pilgrim’s Progress, by John Bunyan
