Why should the church always be on guard?

By Elizabeth Prata

The Lord will build His church. It will never fail. That’s not to say that it won’t be under attack. It’s under attack every day. So the Holy Spirit inspired the Bible authors to warn us in many of the books to stay vigilant.

From the John MacArthur Daily Bible, entry on July 18,

Why should the church always be on guard?

“Paul told the Ephesians that he had declared to them “the whole purpose of God” (Ac 20:27). The entire plan and purpose of God for man’s salvation in all its fullness: divine truths of cre ation, election, redemption, justification, adoption, conversion, sanctification, holy living, and glorification. And now that he was leaving, he gives them a warning.”

“False teachers were already plaguing the churches of Galatia (Gal 1:6) and the Corinthian church (2Co 11:4). “Be on guard for yourselves” (v. 28), a warning that proved true by later events at Ephesus (1Ti 1:3-7, 19-20; 6:20-21; Rev 2:2). Paul repeated this call to self-examination to Timothy when his young son in the faith served as pastor of the Ephesian congregation (1Ti 4:16; 2Ti 2:20-21). The “overseers” are the same as elders and pastors. The word stresses the leaders’ responsibility to watch over and protect their congregations- an appropriate usage in the context of a warning against false teachers. Church rule, which minimizes the biblical authority of elders in favor of a cultural, democratic process, is foreign to the New Testament (1Th 5:12, 13; Heb 13:17).”

“He warns of “savage wolves” (v. 29)-a term borrowed from Jesus (Mt 7:15; 10:16). This metaphor stresses the extreme danger false teachers pose to the church. “From among your own selves” (v. 30). Even more deadly than attacks from outside the church are the defections of those (especially leaders) within the church (1Ti 1:20; 2Ti 1:15; 2:17; Jude 3, 4, 10-13). These wolves would speak “perverse things.” The Greek word means “distorted” or “twisted.” False teachers twist God’s Word for their own evil ends (13:10; 2Pe 3:16).”

“And now I commend you to God and to the word of His grace, which is able to build you up” (v. 32). The Scriptures, the record of God’s gracious dealings with mankind, is the source of spiritual growth for all Christians. And since the church is “the pillar and support of the truth” (1Ti 3:15), its leaders must be familiar with that truth.” –end quoted MacArthur Bible entry


Stay vigilant. Be vigilant of our flesh and kill our own sin. Be vigilant over what we absorb from the world, which is at odds with the Lord Jesus. Stay vigilant over enemies and spies who come into the church, either your physical church or the digital Christian world via speeches, books, podcasts and the like. Jesus commended the church at EPhesus for being vigilant-

I know your deeds and your labor and perseverance, and that you cannot tolerate evil people, and you have put those who call themselves apostles to the test, and they are not, and you found them to be false; and you have perseverance and have endured on account of My name, and have not become weary. (Revelation 2:2-3).

How do we remain on guard but not get weary expending that energy? Rely on the Lord. His sustenance is the word, prayer, and fellowship with the saints. These things revive us.
