It is evident from Scripture, that those who have been born-again, can end up rejecting Jesus Christ, and lose their salvation. This is no theory, but the plain teaching of the Holy Bible. I am going to refer to a passage from the book of Hebrews, and would like the Calvinists to have some honest answers. Hebrews 10:28-31 "Anyone who has rejected Moses’ law dies without mercy on the testimony of two or three witnesses.Of how much worse punishment, do you suppose, will he be thought worthy who has trampled the Son of God underfoot, counted the blood of the covenant by which he was sanctified a common thing, and insulted the Spirit of grace? For we know Him who said, "Vengeance is Mine, I will repay," says the Lord. And again, "The LORD will judge His people." It is a fearful thing to fall into the hands of the living God" There are some, who are under the false impression, that shuch warnings in Scripture are nothing more than "hypothetical", and are in fact not warnings at all. This view, I believe this a delusion, and one that the enemy would like us to hold to. The reality is, that this, and other warnings found in Scripture are indeed what they are, and ought to be heeded by all those who claim to follow the Lord Jesus Christ. The identity of those spoken off in the above passage, is claerly of someone who has been born-again by the Holy Spirit. For, they are clearly said to be "sanctified by the blood of Jesus" (v.29), language that would not have been used for someone who is not born-again. Further, we read in verse 30, where it says of these, that, "the Lord shall judge His people". Again, hardly language used of the unsaved. What are these mentioned in this passage, guilty of? Verse 28 tells us of those who "rejected", or "spurned", the Law of Moses, which in effect, is The Law of God, as He is the Lawgiver. These who treated the Law of God with disdain, were condemned to death with no mercy. Paul, then goes on to speak of the "worse", "more severe" punishment, than those who suffered by rejecting the Law of Moses, were "considered worth of". These "believers" of verse 29, are said to have "trodden under foot the Son of God", which is treat Him with the utmost contempt. They are also guilty of reckoning that the Holy blood of Jesus Christ, by which they had been "sanctified", an "unholy (or common)" thing; and thereby had "insulted" the Holy Spirit. This can only be considered as the ultimate sin against God, which is the "Blasphemy against the Holy Spirit". I personally cannot see this passage refer to someone who is not truly saved, or even to someone who might be just "seeking" for the Truth, but has not as yet decided to follow Christ. The language does not allow for this, and must be taken to refer to those who have been born-agian by the Spirit of God.
