I understand your view but can you align what is being written in scriptures that runs contrary to your view?
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.
See how that branch was of the vine and yet can be taken away and cast forth into the fire?
Then we read how He is warning believers to be ready or else be cut off to be with the unbelievers and they will get certain measure of stripes for not being ready and still called servants as still His servants for when He sends that fire on the earth.
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?
So here we have a cutting and a taken away as having been saved but what? Missing out on the firstfruit of the resurrection for ceasing to abide in Him and thus not being ready to go.
Yet if a saved believer, even a former believer departs from iniquity before the Bridegroom comes, he shall be received as that vessel unto honor in His House but if they do not look to Him for help to depart from iniquity by the time the Bridegroom comes, they will be left behind to die, but their spirts will be with the Lord in Heaven to await for their resurrection after the great tribulation as vessels unto dishonor in His House.
2 Timothy 2:18 Who concerning the truth have erred, saying that the resurrection is past already; and overthrow the faith of some. 19 Nevertheless the foundation of God standeth sure, having this seal, The Lord knoweth them that are his. And, let every one that nameth the name of Christ depart from iniquity. 20 But in a great house there are not only vessels of gold and of silver, but also of wood and of earth; and some to honour, and some to dishonour. 21 If a man therefore purge himself from these, he shall be a vessel unto honour, sanctified, and meet for the master's use, and prepared unto every good work.
So those that have gone astray and those that are saved but fallen into sin in reaping corruption, He will finish His work in those left behind as He will lose none of all the Father has given Him. This explains why there are vessels unto dishonor in His House as they are still saved.
