But again had he not turned what did Paul say? "that the spirit may be saved in the day of the Lord Jesus" You say nothing of the 1st Timothy verse did those two learn not to blaspheme after being turned over to Satan for destruction? We don't know but the same terminology was used for them as was for the man in 1 Corinthians, notice 1 Timothy, "I have delivered unto Satan", verse 1 Corinthians "deliver such an one unto Satan for the destruction of the flesh". Those who are saved and revert to living a sinful life are turned over to satan for destruction of the flesh but Paul stated clearly, "that the spirit may be saved in the day of the Lord Jesus". The man in 1st Corinthians clearly came back but Paul said if he was turned over to satan for destruction of his body the spirit would remain saved.The idea of living like the devil all the way to heaven is one of the logical conclusions of OSAS that Calvinism fights against in its 3 and 5 point versions that insists on not turning a blind eye to the Romans 2:4-13 doctrine of "perseverance".
Your snip reference to 1 Cor 5 is actually not at all making your case because of 2 Corinthians 7 where we see that disfellowship from the body of Christ in 1 Cor 5 - had its intended effect - in that the one disciplined eventually responded with repentance, turning from open sin and rejoining the body of Christ
So let's take you view a minute if OSAS is not biblical then not one person will be saved, not one will go to heaven James 2:10 10 For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all. If you violate just one point of the law your guilty of all and if you died the moment you violated one having been faithful the whole time you would die and go to hell by the teaching of turning back to sin. Matthew 5:28 But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart. Here again if you look on a woman with a thought of lust and have thus committed adultery if not OSAS you look and died that instance you by your teaching would wend up in hell.
But what do we see Jesus say? John 10:
27 My sheep hear my voice, and I know them, and they follow me:
28 And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand.
29 My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand.
30 I and my Father are one.
How does one follow Christ? By believing on Him as John 3:16-18 states "those who believe are not condemned" once in His hand not one person can remove the saved from Christ hand and He and the Father hold us tight. No one is stronger than God, so if you say as many do I"I can remove myself" you are saying God in not Omnipotent because you are saying that you are stronger than God. Notice something very Important about what Jesus stated in verse 28, "I give unto them eternal life" where does salvation come from? Christ gives eternal life and to whom does He give it? Ephesians 2:8 & 9 " For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, 9 not of works, lest anyone should s boast." Christ said He gives eternal life Paul says salvation is the gift of God because of Faith. John 3:
16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved.
18 He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.
Salvation comes by believing on Christ. 1 John 5:13 These things have I written unto you that believe on the name of the Son of God; that ye may know that ye have eternal life, and that ye may believe on the name of the Son of God.
Not one thing about you must live a pure life to keep salvation, Salvation comes to those who believe, not those who through perseverance keep salvation. Salvation is the gift of God to all who believe and once saved you are always saved.
One more point 1 Corinthians 3:
11 For other foundation can no man lay than that is laid, which is Jesus Christ.
12 Now if any man build upon this foundation gold, silver, precious stones, wood, hay, stubble;
13 Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is.
14 If any man's work abide which he hath built thereupon, he shall receive a reward.
15 If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.
The foundation of Salvation is Christ not our works, that is believing on Him. Now there will be believers who face Christ at the Bema or Judgment seat
Romans 14:10 But why dost thou judge thy brother? or why dost thou set at nought thy brother? for we shall all stand before the judgment seat of Christ.
When we stand before Him we will receive our eternal rewards, notice some will have gold, silver and precious stones while others will have wood, hay and straw. I personally believe most will all have a little of both. Those who are saved or as you stated "living like the devil all the way to heaven" will have wood, hay and straw but notice verse 15 what will they have in eternity? "he himself shall be saved" rewards burnt to a crisp nothing to show for being faithful to Christ and living for Him, but they will have salvation. Again Paul says those who suffer loss of loss of the rewards for unspiritual works as a believer will suffer that loss but they will be saved, no question. Not one persons works keeps them saved, but for those we do as lead of the Holy Spisrt we will have great rewards in eternity.
