Rightly dividing the word of truth for those who have not denied the ability of their own entelic, and are not trusting on the Holy Ghost to reveal, will not be able to understand the doctrine that Jesus taught.
Saved according to Greek translators means "delivered". We are delivered eternally, and we are delivered many times as we sojourn here in this world'
1 Tim 2:4, When a regenerated person grows to mature enough to have a knowledge of God's righteousness (the truth) they are delivered from their ignorance of that knowledge. Rom 10:1-3, indicates this by Paul's prayer for the new born babes in Christ that had a zeal of God, but not according to the knowledge of God's righteousness.
2 Pet 3:9, To keep this verse in context, we have to go back to 2 Pet 1, which tells us that Peter was giving this warning to them that have obtained like precious faith. Peter even includes himself in his warning by using the word "us-ward". Peter is telling them that when they commit a sin, that God is longsuffering in bringing them to repentance, not willing that any should perish=death=separation from their fellowship with him. This is not directed to the unregenerate natural man that would never repent of breaking a spiritual law that he cannot discern, and thinks it to be foolishness. 1 Cor 2:14.
Ezek 33:11, The wicked referenced in this verse are regenerated children of God. "death = separation" in this verse God is telling them that he has no pleasure in his children being separated from his fellowship. God has promised us a good and abundant life here on earth if we will follow his commandments and stay in fellowship with him. The straight gate in Matt 7 harmonizes with this, saying those that enter that gate are few, that has found that good and abundant life that he has promised to the faithful that follow his commandments.
