Don't Hastily Endorse Others
1Tim 5:22 "Do not lay hands on anyone hastily, nor share in other people’s sins; keep yourself pure."
That is, do not authorize or endorse the ministry of others without thoroughly checking them out first. For to do so would be to unintentionally share in the sins they commit. And zeal and enthusiasm should not be the primary measure of one's readiness for such positions.
Neither should Christians gullibly accept alleged authority figures on their word only. For Bible commends the Bereans for their skepticism saying, "Now the Bereans were of more noble character than the Thessalonians, for they received the message with great eagerness and examined the Scriptures every day to see if what Paul said was true." Acts 17:11
