That is why there is a damnation of saved believer for not being ready as found abiding in Him & His words in being received to the Marriage Supper in Heaven as His disciples aka vessels unto honor in His House.Some people believe that once you are in the kingdom you are "safe".
Matt 13:41; "The Son of Man will send forth His angels, and they will gather out of His kingdom all stumbling blocks, and those who commit lawlessness,
Even Satan, and the fallen angels were once "in" the kingdom,
Jude 1:6; And angels who did not keep their own domain, but abandoned their proper abode, He has kept in eternal bonds under darkness for the judgment of the great day,
Luke 10:18; And He said to them, "I was watching Satan fall from heaven like lightning.
Ezek 28:13 "You were in Eden, the garden of God; Every precious stone was your covering: The ruby, the topaz and the diamond; The beryl, the onyx and the jasper; The lapis lazuli, the turquoise and the emerald; And the gold, the workmanship of your settings and sockets, Was in you. On the day that you were created They were prepared.
Ezek 28:14 "You were the anointed cherub who covers, And I placed you there. You were on the holy mountain of God; You walked in the midst of the stones of fire.
Ezek 28:15 "You were blameless in your ways From the day you were created Until unrighteousness was found in you.
Ezek 28:16 "By the abundance of your trade You were internally filled with violence, And you sinned; Therefore I have cast you as profane From the mountain of God. And I have destroyed you, O covering cherub, From the midst of the stones of fire.
Ezek 28:17 "Your heart was lifted up because of your beauty; You corrupted your wisdom by reason of your splendor. I cast you to the ground; I put you before kings, That they may see you.
Even Christians will be judged.
1Pet 4:17; For it is time for judgment to begin with the household of God; and if it begins with us first, what will be the outcome for those who do not obey the gospel of God?
Those saints & former believers left behind to die when their spirits will be with the Lord in Heaven awaiting for their resurrection after the great tribulation, they will become as vessels unto dishonor in His House, the vessels of wood & earth.
They are saved, but not safe from God's wrath if they believed they can live in sin. Repeating a post to you from another thread below in case you missed it but is applicable here.
When we see the consequence for not looking to Jesus Christ to help us lay aside every weight & sin to be found abiding in Him daily in running that race, we risk a scourging from the Father.
Hebrews 12:1Wherefore seeing we also are compassed about with so great a cloud of witnesses, let us lay aside every weight, and the sin which doth so easily beset us, and let us run with patience the race that is set before us, 2 Looking unto Jesus the author and finisher of our faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God.
3 For consider him that endured such contradiction of sinners against himself, lest ye be wearied and faint in your minds. 4 Ye have not yet resisted unto blood, striving against sin. 5 And ye have forgotten the exhortation which speaketh unto you as unto children, My son, despise not thou the chastening of the Lord, nor faint when thou art rebuked of him: 6 For whom the Lord loveth he chasteneth, and scourgeth every son whom he receiveth. 7 If ye endure chastening, God dealeth with you as with sons; for what son is he whom the father chasteneth not? 8 But if ye be without chastisement, whereof all are partakers, then are ye bastards, and not sons. 9 Furthermore we have had fathers of our flesh which corrected us, and we gave them reverence: shall we not much rather be in subjection unto the Father of spirits, and live? 10 For they verily for a few days chastened us after their own pleasure; but he for our profit, that we might be partakers of his holiness. 11 Now no chastening for the present seemeth to be joyous, but grievous: nevertheless afterward it yieldeth the peaceable fruit of righteousness unto them which are exercised thereby.
But when does that scourging or that whipping from the Father takes place? Jesus says when saved believers are left behind for not being ready to go as found abiding in Him & His words as His disciples.
Luke 12:40 Be ye therefore ready also: for the Son of man cometh at an hour when ye think not. 41 Then Peter said unto him, Lord, speakest thou this parable unto us, or even to all? 42 And the Lord said, Who then is that faithful and wise steward, whom his lord shall make ruler over his household, to give them their portion of meat in due season? 43 Blessed is that servant, whom his lord when he cometh shall find so doing. 44 Of a truth I say unto you, that he will make him ruler over all that he hath. 45 But and if that servant say in his heart, My lord delayeth his coming; and shall begin to beat the menservants and maidens, and to eat and drink, and to be drunken; 46 The lord of that servant will come in a day when he looketh not for him, and at an hour when he is not aware, and will cut him in sunder, and will appoint him his portion with the unbelievers. 47 And that servant, which knew his lord's will, and prepared not himself, neither did according to his will, shall be beaten with many stripes. 48 But he that knew not, and did commit things worthy of stripes, shall be beaten with few stripes. For unto whomsoever much is given, of him shall be much required: and to whom men have committed much, of him they will ask the more. 49 I am come to send fire on the earth; and what will I, if it be already kindled?
John 15:1I am the true vine, and my Father is the husbandman. 2 Every branch in me that beareth not fruit he taketh away: and every branch that beareth fruit, he purgeth it, that it may bring forth more fruit. 3 Now ye are clean through the word which I have spoken unto you. 4 Abide in me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye abide in me. 5 I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing. 6 If a man abide not in me, he is cast forth as a branch, and is withered; and men gather them, and cast them into the fire, and they are burned. 7 If ye abide in me, and my words abide in you, ye shall ask what ye will, and it shall be done unto you. 8 Herein is my Father glorified, that ye bear much fruit; so shall ye be my disciples.
Running that race is not for obtaining salvation but for the high prize of our calling for that incorruptible crown by His grace & by His help so as to avoid being a castaway, as a vessel unto dishonor, but still in His House.
1 Corinthians 9:24 Know ye not that they which run in a race run all, but one receiveth the prize? So run, that ye may obtain. 25 And every man that striveth for the mastery is temperate in all things. Now they do it to obtain a corruptible crown; but we an incorruptible. 26 I therefore so run, not as uncertainly; so fight I, not as one that beateth the air: 27 But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway.
When we discern with Him the ramification of this truth in His words below, then OSAS is true, but not every saved believer will be ready to go when the Bridegroom comes but they will wished they had been ready.
Ephesians 4:30 And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.
