If someone is "hard-headed" about a doctrine that is not backed up by the word of the Lord, then they are in the wrong. They are holding their own opinion to be the final authority rather than the word of God.
And I have asked this so many time, if you where studying something and God told you that you where wrong, who would you believe, God or the Bible?? So few are willing to answer that question. Christians demand scripture, so the devil gives it to them, he knows the bible far better than any man, remember Jesus in the desert.
Mat 4:6 And saith unto him, If thou be the Son of God, cast thyself down: for it is written, He shall give his angels charge concerning thee: and in their hands they shall bear thee up, lest at any time thou dash thy foot against a stone.
God set Jesus, His Word above Him self,
Col 1:18 And he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all things he might have the preeminence.
Col 1:19 For it pleased the Father that in him should all fulness dwell;
it is man, that demands God agree with the bible, " I shall have no other Gods before ME" God gave us His Spirit so we could all learn from Him
Joh_6:45 It is written in the prophets, And they shall be all taught of God. Every man therefore that hath heard, and hath learned of the Father, cometh unto me.
But one must first open the door,
Rev_3:20 Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me.
so few willing to open and let Him in.
None of us are right, God is right, Jesus is right, and the Holy Spirit who can only say and do what He is told is right, because they are all in agreement, but few agree with God.
I have being shown for 17 years why I am wrong about Him by Him, religion and man have mocked Him for years.
