The gospel ministry

The following quote is from Benjamin Wadsworth's introduction to The Gospel Ministry by Thomas Foxcroft:
The right performance of this work [of gospel ministry] is attended with many and great difficulties, partly from the various, frequent, furious assaults of Satan; partly from the lusts of men, variously discouraging or opposing it; and partly from the weaknesses and remaining corruptions of even the best of those who engage in it. Yet it is a work that is very honorable in itself, and of vast weight and importance. It must be thought so if we rightly consider that it is the infinitely great, glorious, holy and heart-searching God who (in His providence) calls and commissions men to this work; that the main scope of the work is to batter down Satan's kingdom, to pull down the strongholds of lust in the hearts of men, to promote the glory of divine grace through Christ in saving men's precious, immortal souls, one of which is more worth than a world; and that those who engage in this work must give a strict account of their management to that God who employs them, who can't be deceived and won't be mocked, and who will require at their hands the blood of those souls who perish through their neglect, as well as graciously and abundantly reward them if they are faithful.
What fearful and wonderful labour this is! Does the weight of your work press upon you, in the best and right sense? May God spare us from making shipwreck of our own faith, and being mere sirens to call other men on to the rocks of eternal destruction, and may we prove faithful and fruitful in the discharge of all our duties.
