And it is necessary he also have a proper testimony from those outside, in order that he does not fall into disgrace and a snare from the devil (1 Timothy 3:7).
A man who desires the position of a bishop must also have a good testimony among those outside the congregation. He is to be recognized as one who conducts himself properly, giving evidence through his actions of the genuineness of his faith.
This external testimony protects him from falling into disgrace, which could be used to humiliate or dishonor him for not living according to the very truths he claims to believe and teach. Moreover, it serves as a safeguard against falling into the snare of the devil, who seeks to entrap Christians to carry out his will (2 Timothy 2:26). Such entrapment often involves the promotion of teachings contrary to the truth, driven by youthful cravings, foolish and ignorant arguments, and contentious behavior.
Unbelievers will often seek to disgrace believers, especially those in positions of teaching and leadership. How many pastors have fallen due to their failure to maintain a proper testimony among those who are outside, entangling themselves in the affairs and rhetoric of the world? They teach one thing, yet are found engaging in the very practices they condemn—or worse, in deeds even more corrupt—among those outside the assembly.
