How do you ever get that it is dangerous?
I suppose "dangerous" is maybe too loaded of a word, but should we assume that Noah let out the Holy Spirit from the ark since in the NT that is the form the Holy Spirit took in descending upon Jesus?
Anyone can become the person Jesus saves.
What scripture shows this? When I read what Jesus says about sheep, I find an underlying identification that is unavoidable and seemingly unchangeable. That is, a sheep is a sheep is a sheep and a goat is a goat is a goat (even if dressed up like a sheep). Even before it goes astray, it's a sheep. Even after it goes astray it's a sheep. The point being that those who are His sheep follow Him and will not follow another. Even if they stray. And those that Jesus casts away? He says He
never knew them. I won't say who (specifically) can and cannot be saved, but there is something deeper here at work that goes well beyond the will of man.
Matthew 18:3 And he said: "Truly I tell you, unless you change and become like little children, you will never enter the kingdom of heaven.
I looked up "change" in that verse. The KJV renders it "be converted". The underlying Greek has it (in that verse) as a passive verb. In other words it happens
to the person in question. The version you quoted implies it is the individual's responsibility to change.
Salvation has always been the same. It has always been that way. In the time of Adam and Eve, it was about believing and obeying God. In the time of Cain and Abel, it was about believing and obeying God. In the time of Noah, it was about believing and obeying God. In the time of Abraham, it was about believing and obeying God, in the time of Jesus, it was about believing and obeying God. In the time of Paul, it was about believing and obeying God. In our times now, it is about believing and obeying God.
But it is
not about self-improvement. Self-change to be acceptable to God.
The scripture is about God’s people obeying, if they do not obey, it will be a dreadful thing.
Read carefully until you get up to the part about it being a dreadful thing.
26 If we deliberately keep on sinning after we have received the knowledge of the truth, no sacrifice for sins is left,
27 but only a fearful expectation of judgment and of raging fire that will consume the enemies of God.
28 Anyone who rejected the law of Moses died without mercy on the testimony of two or three witnesses.
29 How much more severely do you think a man deserves to be punished who has trampled the Son of God under foot, who has treated as an unholy thing the blood of the covenant that sanctified him, and who has insulted the Spirit of grace?
30 For we know him who said, "It is mine to avenge; I will repay," and again, "The Lord will judge his people."
31 It is a dreadful thing to fall into the hands of the living God.
If you read that as stronger than Jesus' statement about His sheep NOT following another, then you are resting in the law and threatenings to encourage obedience. One who is the Lord's knows this implicitly and is more concerned about obeying Him out of love - because God has changed him (or her). Unless ye be converted...
