Looking diligently lest any man fail of the grace of God; lest any root of bitterness springing up trouble you…
To prevent this danger they must look diligently. To this end —
1. Every man must have a care of himself, and look to his own soul.
2. They must watch one over another, and if they see any inclining to apostasy, or beginning to doubt of, or decline his profession, they must, by good example, instruction, admonition, reproof, and exhortation, seek to reform him.
3. The minister of the gospel being trusted with man's soul, must be very watchful above all other; must exhort, reprove, and by his wholesome doctrine, inform the ignorant, strengthen the weak, reform the erroneous, encourage the faint, and suffer no such bitter root to spring up amongst his people.
4. They that have the power of discipline, upon information, must by admonition and lighter censures first seek to reclaim a sinning brother; and if so, they cannot rectify him, they must cast him out, lest others be infected.
