The goal of our instruction is love from a pure heart

The goal of the Apostle Paul was for believers to be “filled with love that comes from a pure heart, a clear conscience, and genuine faith.” If your fellowship is filled with this kind of gentle instruction, then thank the Lord for his many blessings. But, if your fellowship is filled with “foolish, ignorant arguments that only start fights,” that is not what God wants. If you cannot “gently instruct those who oppose the truth,” then maybe it’s time to “have nothing more to do with them.”

Warning against False Teaching

When I left for Macedonia, I urged you to stay there in Ephesus and stop those whose teaching is contrary to the truth. Don’t let them waste their time in endless discussion of myths and spiritual pedigrees. These things only lead to meaningless speculations, which don’t help people live a life of faith in God.
The purpose of my instruction is that all believers would be filled with love that comes from a pure heart, a clear conscience, and genuine faith. But some people have missed this whole point. They have turned away from these things and spend their time in meaningless discussions. They want to be known as teachers of the law of Moses, but they don’t know what they are talking about, even though they speak so confidently. (1 Timothy 1:3-7)

If you explain these things to the brothers and sisters, Timothy, you will be a worthy servant of Christ Jesus, one who is nourished by the message of faith and the good teaching you have followed. Do not waste time arguing over godless ideas and old wives’ tales. Instead, train yourself to be godly. (1 Timothy 4:6-7)

Teach these things, Timothy, and encourage everyone to obey them. Some people may contradict our teaching, but these are the wholesome teachings of the Lord Jesus Christ. These teachings promote a godly life. Anyone who teaches something different is arrogant and lacks understanding. Such a person has an unhealthy desire to quibble over the meaning of words. This stirs up arguments ending in jealousy, division, slander, and evil suspicions. These people always cause trouble. Their minds are corrupt, and they have turned their backs on the truth. To them, a show of godliness is just a way to become wealthy. (1 Timothy 6:3-5)

Again I say, don’t get involved in foolish, ignorant arguments that only start fights. A servant of the Lord must not quarrel but must be kind to everyone, be able to teach, and be patient with difficult people. Gently instruct those who oppose the truth. Perhaps God will change those people’s hearts, and they will learn the truth. Then they will come to their senses and escape from the devil’s trap. For they have been held captive by him to do whatever he wants. (2 Timothy 2:23-26)

For a time is coming when people will no longer listen to sound and wholesome teaching. They will follow their own desires and will look for teachers who will tell them whatever their itching ears want to hear. They will reject the truth and chase after myths. (2 Timothy 4:3-4)

The worst offenders are religious people who listen to myths

For there are many rebellious people who engage in useless talk and deceive others. This is especially true of those who insist on circumcision for salvation. They must be silenced, because they are turning whole families away from the truth by their false teaching. And they do it only for money. Even one of their own men, a prophet from Crete, has said about them, “The people of Crete are all liars, cruel animals, and lazy gluttons.” This is true. So reprimand them sternly to make them strong in the faith. They must stop listening to Jewish myths and the commands of people who have turned away from the truth. (Titus 1:10-14)

Do not get involved in foolish discussions about spiritual pedigrees or in quarrels and fights about obedience to Jewish laws. These things are useless and a waste of time. If people are causing divisions among you, give a first and second warning. After that, have nothing more to do with them. For people like that have turned away from the truth, and their own sins condemn them. (Titus 3:9)
