O Soul, Consider This Deeply!

The quote I have below is a foot note from The Pilgrim's Progress, written by John Bunyan:

"O soul, consider this deeply: it is the life of a Christian that carries more conviction and persuasion than his words. Though, like an angel, you talk of Christ, of the gospel, of the doctrines of grace, and of heaven; yet, if you indulge devilish tempers, and live under the power of any sinful s and passions, you will hereby harden others against the things of God and prevent their setting out in the ways of God. Study and pray to be a consistent walker in the ways of holiness; else, all is but windy profession and airy talk. O how much harm is done to Christ's cause by the unholy walk of many professors!"
