Good to have you back, dear brother. As usual, you have provided another thorough and sound Biblical account for another important, and very relevant doctrine. A Biblical teaching all should prayerfully consider and earnestly heed.
This verse came to my mind.
2 Timothy 3:7 Ever learning, and never able to come to the knowledge of the truth.
Could the habitual and blind heretick actually be lost. Why do people reject plain, simple, straight truth in the word of God? Why do men, after reasonable and sound Biblical persuasion refuse to submit to the truth? It's more than a proud heart. It's a mind that has the inability to be "spiritual."
1 Corinthians
2:12 Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God.
2:13 Which things also we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual.
2:14 But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned.
2:15 But he that is spiritual judgeth all things, yet he himself is judged of no man.
2:16 For who hath known the mind of the Lord, that he may instruct him? But we have the mind of Christ.
If you have a difficult time understanding the word of God, if the Holy Spirit is not teaching you through the word, if you ignore and debate the sound teaching by many on this Forum who are in unity and agreement, I counsel you to:
2 Corinthians 13:5 Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates?
