I don’t need Calvinist logic or any of the petals from the tulip to believe in eternal security.
As an example, the text following, that might seem like it teaches holding on to salvation as if it could be lost, actually shows the opposite.
Hebrews 10:16-31
This is the covenant that I will make with them after those days, saith the Lord, I will put my laws into their hearts, and in their minds will I write them; And their sins and iniquities will I remember no more.
(God forgave our sins. All of them before they were committed.) Now where remission of these is, there is no more offering for sin.
(There is no more offering because there is remission of sin. There is no sin to offer for. This is in the context at the beginning of the chapter. “Once for all.”)
Having therefore, brethren, boldness to enter into the holiest by the blood of Jesus, By a new and living way, which he hath consecrated for us, through the veil, that is to say, his flesh; And having an high priest over the house of God; Let us draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil conscience, and our bodies washed with pure water.
(The bold ness can only come by assurance of salvation. A lasting peace that is dependent upon the work of Christ. But then he doesn’t just say assurance, he says full assurance. Complete assurance. At this point Reformed theology logic isn’t necessary. It is here in plain English. The sprinkling of the heart is a reference to the blood of Christ that was offered on the mercy seat in heaven. The sprinkling of the heart leads us to a clear conscience. At this point the Christian is guiltless because the blood is applied.)
(Now in the following verses it tells us to hold on to the profession of our faith. And exhort to good works. Why? The rest of the passage tells us. )
Let us hold fast the profession of our faith without wavering; (for he is faithful that promised

And let us consider one another to provoke unto love and to good works: Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching.
For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,
(There is no more sacrifice for sins because they are gone, covered under the blood. One sacrifice for all sins.) But a certain fearful looking for of judgment and fiery indignation,
(“whom the Lord loveth he chasteneth”) which shall devour the adversaries
(opposed, those doing what is sin). He that despised Moses' law died without mercy under two or three witnesses: Of how much sorer punishment, suppose ye, shall he be thought worthy, who hath trodden under foot the Son of God, and hath counted the blood of the covenant, wherewith he was sanctified, an unholy thing, and hath done despite unto the Spirit of grace? For we know him that hath said, Vengeance belongeth unto me, I will recompense, saith the Lord. And again, The Lord shall judge his people. It is a fearful thing to fall into the hands of the living God.
(All this judgment speaks of an answer in this lifetime. All through Hebrews the old and new covenants are compared. The guilty under the law were put to death. But they were guilty of the Law. Christian’s are now guilty of the blood of Christ. They have known what Christ has done for them and walked all over Him. By comparison, from the first covenant to the second, who has the greater stench of offense? The question is asked, what punishment do you think he is now worthy of. I find it an intentional rhetorical question. It doesn’t say, “ you know what he’s going to get for that now don’t you?” Or, “how much more punishment will he get?”
Instead, without mistake, it says “thought worthy.” It is all a matter of personal judgment at this point.
But then he says God will judge HIS people. They are not children of the devil. They are His own children who are being chastised.
In comparison with the first covenant, I find the chastening to be related to this lifetime on earth and not related to eternity.)
