Romans 12:1 I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service. KJV
Don't know what Bible version you are using that added "of worship" to that verse.
Just so you know and to clarify what I am sharing;
The pre great tribulation rapture event is when God will judge His House first. 1 Peter 4:17
Those found reprobates are disqualified and left behind for being workers of iniquity, BUT they are still His servants and thus still saved,
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?
In that day of judgment on the House of God, see how the Lord will judge every believer by what they build on that foundation laid by Jesus Christ.
1 Corinthians 3:10 According to the grace of God which is given unto me, as a wise masterbuilder, I have laid the foundation, and another buildeth thereon.
But let every man take heed how he buildeth thereupon. 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. 16 Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you? 17 If any man defile the temple of God, him shall God destroy; for the temple of God is holy, which temple ye are.
So any works of iniquity on that foundation that denies Him, He will deny them, but He still abides in them that gets left behind, even in former believers that would verbally deny Him.
Titus 1:16 They profess that they know God; but in works they deny him, being abominable, and disobedient, and unto every good work reprobate.
This is why His disciples are to call others that are living in sin or practicing religious works that deny Him to repent with His help so they too may obtain that eternal glory of being that vessel unto honor in His House to be received by Him at the pre great tribulation rapture event.
2 Timothy 2:10 Therefore I endure all things for the elect's sakes, that they may also obtain the salvation which is in Christ Jesus with eternal glory. 11 It is a faithful saying: For if we be dead with him, we shall also live with him: 12 If we suffer, we shall also reign with him:
if we deny him, he also will deny us: 13 If we believe not, yet he abideth faithful: he cannot deny himself.
1
8 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 no loss of salvation as the vessels unto dishonor are still in His House but missed out on being partakers of the firstfruit of the resurrection.
Like the prodigal son that gave up his first inheritance for a meal and can never get it back, he is still son.
But better to heed the call to continue the reformation that Luther did not finish to abstain from all appearances of evil than to continue as is.
2 Corinthians 5:7 (For we walk by faith, not by sight
8 We are confident, I say, and willing rather to be absent from the body, and to be present with the Lord. 9 Wherefore we labour, that, whether present or absent, we may be accepted of him. 10 For we must all appear before the judgment seat of Christ; that every one may receive the things done in his body, according to that he hath done, whether it be good or bad. 11 Knowing therefore the terror of the Lord, we persuade men; but we are made manifest unto God; and I trust also are made manifest in your consciences.
Anyway, this is how saved believers are still saved by the grace of God and yet have works that deny Him on that foundation for why they are disqualified to attend the Marriage Supper in Heaven at the pre great tribulation rapture event when God shall judge His House first.
1 Peter 4:1Forasmuch then as Christ hath suffered for us in the flesh, arm yourselves likewise with the same mind: for he that hath suffered in the flesh hath ceased from sin; 2 That he no longer should live the rest of his time in the flesh to the lusts of men, but to the will of God. 3 For the time past of our life may suffice us to have wrought the will of the Gentiles, when we walked in lasciviousness, lusts, excess of wine, revellings, banquetings, and
abominable idolatries: 4 Wherein they think it strange that ye run not with them to the same excess of riot, speaking evil of you:
12 Beloved, think it not strange concerning the fiery trial which is to try you, as though some strange thing happened unto you: 13 But rejoice, inasmuch as ye are partakers of Christ's sufferings; that, when his glory shall be revealed, ye may be glad also with exceeding joy. 14 If ye be reproached for the name of Christ, happy are ye; for the spirit of glory and of God resteth upon you: on their part he is evil spoken of, but on your part he is glorified. 15 But let none of you suffer as a murderer, or as a thief, or as an evildoer, or as a busybody in other men's matters. 16 Yet if any man suffer as a Christian, let him not be ashamed; but let him glorify God on this behalf. 17 For the time is come that judgment must begin at the house of God: and if it first begin at us, what shall the end be of them that obey not the gospel of God? 18 And if the righteous scarcely be saved, where shall the ungodly and the sinner appear? 19 Wherefore let them that suffer according to the will of God commit the keeping of their souls to him in well doing, as unto a faithful Creator.
May God bless you in the hearing of His words and Jesus Christ enabling you to follow Him.
