We are to warn the people of false doctrine, and if you do not want to believe what we say, you do not have to.
Ezekiel 3:17-21 | English Standard Version (ESV)
17 “Son of man, I have made you a watchman for the house of Israel. Whenever you hear a word from my mouth, you shall give them warning from me. 18 If I say to the wicked, ‘You shall surely die,’ and you give him no warning, nor speak to warn the wicked from his wicked way, in order to save his life, that wicked person shall die for[a] his iniquity, but his blood I will require at your hand. 19 But if you warn the wicked, and he does not turn from his wickedness, or from his wicked way, he shall die for his iniquity, but you will have delivered your soul. 20 Again, if a righteous person turns from his righteousness and commits injustice, and I lay a stumbling block before him, he shall die. Because you have not warned him, he shall die for his sin, and his righteous deeds that he has done shall not be remembered, but his blood I will require at your hand. 21 But if you warn the righteous person not to sin, and he does not sin, he shall surely live, because he took warning, and you will have delivered your soul.”
