If we think our fellowship depends on walking in the light, then we are denying what was revealed to Paul about God's faithfulness toward us in 1 Corinthians 1:8-9.
There are 2 ways for Him to confirm us unto the end, as a vessel unto honor in His House for those abiding in Him and His words or as a vessel unto dishonor in His House for not abiding in Him & His words. Walking in darkness runs the risk of not being part of the firstfruits of the resurrection as vessels unto honor to be received when the Bridegroom comes for the abiding bride of Christ, but cut off and left behind to be resurrected later on after the great tribulation, but both are in His House and that depends on how we build on that foundation which Jesus will judge.
So there is a terror of the Lord to take heed of for why Jesus warned believers to be ready or else in "when" & "how" we will be received, brother.
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.
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.
Believers will be cut off for not abiding in Him, but in spite of the weeping and gnashing of their teeth over being left behind, this is why God will wipe the tears from their eyes since a miracle will be needed to get past that great loss for being damned forever as that vessel unto dishonor In His House, but that is the Lord confirming them unto the end. Why are there vessels unto dishonor in His House? To testify to the power of God in salvation for all those who believe in Him, even in His name as that is God confirming the least in the kingdom of God.
Matthew 5: 19 Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.
So does a believer feel "lucky" to continue to live in sin?
Hebrews 10:30 For we know him that hath said, Vengeance belongeth unto me, I will recompense, saith the Lord. And again, The Lord shall judge his people.31 It is a fearful thing to fall into the hands of the living God.
Hebrews 12: 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.
The prodigal son is still son in spite of giving up his inheritance for wild living, but the loss is still there for he can never get that first inheritance back just like Esau could not.
