I'm not making this post to try to invite others to debate me; I'm honestly just interested in the "real world" beliefs of those who believe salvation can be lost. I'm sure the debate will naturally flow.
If you believe it is possible to lose salvation . . .
1) What causes you to lose it?
2) Is there a chance to regain it?
3) Does this belief cause you emotional distress (e.g. anxiety)?
4) Is there anything you would like to explain or clarify?
There simply is no case for "losing salvation."
Those who think salvation can be lost do not understand what salvation in Christ is in the first place.
I will address question four, as it is the only valid question I see given.
The first thing to understand is that man is born outside of relationship with God. This is the result of the Fall, and all Adam's descendants are born spiritually dead, because spiritual life is only possible through union with God. So every man that is born (and this includes both male and female) has a need for the Life only God can give. When a man is given this life is it accomplished by that person being immersed into God Himself. While many reject it, the fact is that it was not until Pentecost that this Life was bestowed upon men. They balk at the thought that men like Abraham, Moses, and David did not have spiritual life. That is only partly true, because we understand that the Spirit of God has always worked in the hearts and lives of men. But, we cannot overlook the truth taught by Christ which clearly states that immersion into God would not take place until the Comforter came.
So when a man is born again we understand that he is new, and has life...because he is placed into God. All men prior to the Cross offered up the deaths and blood of animals for the temporary atonement for sin, which is contrasted with the Sacrifice of Christ which makes men complete in regard to sacrifice for sin forever:
Hebrews 10:14
King James Version (KJV)
14 For by one offering he hath perfected for ever them that are sanctified.
This is, in my view, the clearest statement of Eternal Security in all of Scripture. The First Century Jew would have understood what the writer was conveying more clearly than those reading a translation. The "perfection" here is contrasted with a previous statement:
Hebrews 10
King James Version (KJV)
1 For the law having a shadow of good things to come, and not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect.
2 For then would they not have ceased to be offered? because that the worshippers once purged should have had no more conscience of sins.
3 But in those sacrifices there is a remembrance again made of sins every year.
4 For it is not possible that the blood of bulls and of goats should take away sins.
The Old Testament Saint was indeed saved by grace, and his eternal destination just as sure as our own, but, that does not mean that we ascribe to them a status of being born again redeemed followers of Christ. The writer also makes this clear here:
Hebrews 9:12-15
King James Version (KJV)
12 Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us.
13 For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh:
14 How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?
15 And for this cause he is the mediator of the new testament, that by means of death, for the redemption of the transgressions that were under the first testament, they which are called might receive the promise of eternal inheritance.
The "First Testament" mentioned here is the Covenant of Law. No-one was saved through the Law, this is an impossibility, as Paul makes clear often in his writings.
Here is a similar statement to that above from Romans:
Romans 3:20-25
King James Version (KJV)
20 Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin.
21 But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets;
22 Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference:
23 For all have sinned, and come short of the glory of God;
24 Being justified freely by his grace through the redemption that is in Christ Jesus:
25 Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God;
Many today confuse the teaching of Scripture and think men are saved by faith through grace, when in fact they are saved by the grace of God only. salvation is a gift, it is not earned, and therefore cannot be forfeited.
Hebrews 10:14
King James Version (KJV)
14 For by one offering he hath perfected for ever them that are sanctified.
Christ did what the Law could not do, he brought completion to remission of sins. When the Writer states that "He has perfected forever" those who are sanctified, he means that the completion brought is eternal.
God bless.
