Pilgrim, I have no quibble with your reply, for I agree with what you wrote. But your words prompted me to explain why I used the term "Repentance" instead of "changing the mind" in the thread title. The most common use of the term is as you wrote. Yet, a couple passages illustrate how I meant the word as a comparison between the more literal KJV compared to the dynamic equivalence REB.

"For John came unto you in the way of righteousness, and ye believed him not: but the publicans and the harlots believed him: and ye, when ye had seen it, repented not afterward, that ye might believe him." (Matt 21:32 KJV)

"For when John came to show you the right way to live, you did not believe him, but the tax-collectors and prostitutes did; and even when you had seen that, you did not change your minds and believe him." (Matt 21:32 REB)

"But what think ye? A certain man had two sons; and he came to the first, and said, Son, go work to day in my vineyard. He answered and said, I will not: but afterward he repented, and went. And he came to the second, and said likewise. And he answered and said, I go, sir: and went not." (Matt 21:28-30 KJV)

"‘But what do you think about this? There was a man who had two sons. He went to the first, and said, 'My son, go and work today in the vineyard.' 'I will, sir,' the boy replied; but he did not go. The father came to the second and said the same. 'I will not,' he replied; but afterwards he changed his mind and went." (Matt 21:28-30 REB)

The impression of the word "repentance" is a much more serious thing than simply "change of mind". I intended that impression. I totally reject the idea expressed so often, "That's just your interpretation!" If the word of God is nothing more than a man's interpretation rather than truth, it does not mean much. Foundationally I see only two options: What we believe is God's truth, or it is Satan's lie. It is true there may be degrees of danger in what the lie is, but it is either true or a lie.

In my background, it was changing my mind about whether faith and repentance are something inherent within me as a natural man, or a prevenient grace given to every man that just needed exercise, or is it a particular gift of God? My earlier years were not in a strongly Arminian church, but still the source of a believer's faith and repentance was not clearly taught and that makes for some serious differences in belief. When it comes to our perseverance, the fact that our faith and repentance is God's gift is a sure foundation; especially if your life shows the evidence of faith over time. What a true comfort that is.

The other major error I learned early was dispensationalism. That belittled the work of Christ and the New Covenant. In some ways it was an escapism from the struggles of our pilgimage here below. It reverted back to the Old Covenant and Judaism as a goal which is heresy. Oddly, it was much more difficult to study out of that heresy than it was to accept the sovereignty of God in salvation.

I mentioned studying hermeneutics, and part of learning that is seeing the examples of men of God in how they reason. My first major source of information about God's sovereignty in salvation was in The Reformed Doctrine of Predestination by Loraine Boettner. What solid reasoning from the word of God that was! Along these lines, I found the old Puritan Matthew Poole reasons so well. Over time the solid reasoning from the scriptures of a particular man of God comes to build a respect in our mind and for me Poole has my respect.

Let me wrap this up by remarking, when we are sitting around the campfire on the trout stream chatting with a friend and it comes to belief, even that chat convey's truth or a lie. I am responsible for it. I take that as a very serious matter. I agree that individualism can be dangerous if we ignore what you wrote: "When one comes to a belief/view that contradicts the belief/doctrine held by such sources that cross denominational lines, then you should be moved to reconsider your personal belief and doubt its verity." Amen

When I read these men of God out of the past, I have learned to be cautious about definitions and find it helps to use the 1828 Webster's Dictionary to get closer to the time frame of reference. I hope I have clarified my intent in the OP.
