Fuller refers to Beddome

In the works of Andrew Fuller there is an item headed
LXIX. THE YOUNG MINISTER EXHORTED TO MAKE FULL PROOF OF HIS MINISTRY.
It is a sketch of a sermon addressed "to the Students of the Stepney Academical Institution" taking the text "But watch thou in all things, endure afflictions, do the work of an evangelist, make full proof of thy ministry. For I am now ready to be offered, and the time of my departure is at hand." (2 Tim. 3:5, 6).

He talks about
(1) The Work Itself to which you are devoted.

(2) The DUTIES INCULCATED AS NECESSARY TO THE DISCHARGE OF THE MINISTRY. These will be found to consist in four things:

1. Vigilance

2. Patience

3. Activity in the great work of evangelizing men

4. Fidelity in discharging your trust

He then says

"But here allow me to be a little more particular. If you would make full proof of your ministry you must attend

(1) To personal religion.—This is often inculcated by the apostle.—"Take heed to yourselves, and to all the flock."—"Take need to thyself and to thy doctrine," &c. Many people will take our personal religion for granted; as though a man who teaches others must needs be religious himself: but woe unto us if we reason in this way. Tremble at the idea of being & graceless minister —a character, it is to be feared, not very unfrequent! To what is it owing that some of our churches have been prejudiced against an educated ministry? I may be told to their ignorance; and in part it is so; but in part it is owing to other causes. The lightness, the vanity, the foppery, and the irreligion of some young men have produced not only this effect, but an abhorrence of the very worship of God, as by them administered. Who were ever known to be prejudiced against a Pearce, a Francis, or a Beddome, on account of their education? If there were individuals of this description, let them be disregarded as ignorant, and let them be told that vicious characters are found among the uneducated as well as the educated. But be it your concern, my dear young men, to shun these evils. The instructions which you receive, if consecrated to Christ, will be a blessing to you; but, if your object be to shine before men, they will be a curse. ...
