Pay No Attention to those who Promote Myths
Titus 1:14 and will pay no attention to Jewish myths or to the commands of those who reject the truth.
Now while it appears these false teachers were primarily unconverted Cretan Jews, there are elsewhere general commands concerning avoiding myths, such as he commanded to Timothy, “Have nothing to do with godless myths and old wives’ tales; rather, train yourself to be godly.”1Tim 4:7 and “As I urged you when I went into Macedonia, stay there in Ephesus so that you may command certain men not to teach false doctrines any longer nor to devote themselves to myths and endless genealogies. These promote controversies rather than God’s work-- which is by faith.” 1Tim 1:3,4
“Preach the Word; be prepared in season and out of season; correct, rebuke and encourage-- with great patience and careful instruction. For the time will come when men will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear. They will turn their ears away from the truth and turn aside to myths.” 2Tim 4:2-4
Along with promoting myths, these also command Christians concerning their way of life. One thing that can help Christians keep themselves from such influence is to be "Berean". “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 Scrutinize everything in light of the Word of God.
