Consider this though if I am right(or anyone else for that matter) when you are with Lord and he asks why did you not listen to his word and accept the doctrine he sent you? What will you say? He sent out preachers into the world so that all may hear his doctrine and after having heard the true word we become accountable for it becoming justified by accepting it or becoming damned through denying it.
Romans 10:14-18
14 How then shall they call on him in whom they have not believed? and how shall they believe in him of whom they have not heard? and how shall they hear without a preacher?
15 And how shall they preach, except they be sent? as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things!
16 But they have not all obeyed the gospel. For Esaias saith, Lord, who hath believed our report?
17 So then faith cometh by hearing, and hearing by the word of God.
18 But I say, Have they not heard? Yes verily, their sound went into all the earth, and their words unto the ends of the world.
2 Peter 2:21
21For it had been better for them not to have known the way of righteousness, than, after they have known it, to turn from the holy commandment delivered unto them.
How do we know they are right and the messenger true? By trying the doctrine they bring by the word of God, that is the only way to know the truth.
2 Preach the word; be instant in season, out of season; reprove, rebuke, exhort with all long suffering and doctrine.
16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
It is not about whether we ourselves agree with the word being brought it is about whether or not the word of God agrees the word brought. If you find fault with what I have written show me how I am wrong with strong doctrine, sparing nothing, and with all long suffering, reprove me and correct what I have said. That is what we are called to do, so that in the day of judgment we can stand before the lord and say, We rebuked and corrected those in error and accepted and kept your pure doctrine delivered by your true messengers.
God bless and guide you.
