biblically speaking...why or why not?
Jesus is praying....
John 17: 8For I have given unto them the words which thou gavest me; and they have received them, and have known surely that I came out from thee, and they have believed that thou didst send me. 9I pray for them: I pray not for the world, but for them which thou hast given me; for they are thine. 10And all mine are thine, and thine are mine; and I am glorified in them. 11And now I am no more in the world, but these are in the world, and I come to thee. Holy Father, keep through thine own name those whom thou hast given me, that they may be one, as we are. 12While I was with them in the world, I kept them in thy name: those that thou gavest me I have kept, and none of them is lost, but the son of perdition; that the scripture might be fulfilled. 13And now come I to thee; and these things I speak in the world, that they might have my joy fulfilled in themselves.
John 6:70Jesus answered them, Have not I chosen you twelve, and one of you is a devil? 71He spake of Judas Iscariot the son of Simon: for he it was that should betray him, being one of the twelve.
Reads like Judas was lost. It is a comfort knowing that He can lose no one else as promised.
John 3: 38For I came down from heaven, not to do mine own will, but the will of him that sent me. 39And this is the Father's will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day. 40And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day.
Still, Jesus warned of false prophets that can mislead to take our eyes off of Jesus.. even for a moment so that is why believers are still called to heed the commandment in His invitation to avoid false prophets and false spirits:
John 14:6Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.
Luke 13:24Strive to enter in at the strait gate: for many, I say unto you, will seek to enter in, and shall not be able.
2 Timothy 2:11It is a faithful saying: For if we be dead with him, we shall also live with him: 12If we suffer, we shall also reign with him: if we deny him, he also will deny us: 13If we believe not, yet he abideth faithful: he cannot deny himself. 14Of these things put them in remembrance, charging them before the Lord that they strive not about words to no profit, but to the subverting of the hearers. 15Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.....19Nevertheless 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. 20But 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. 21If 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. 22Flee also youthful lusts: but follow righteousness, faith, charity, peace, with them that call on the Lord out of a pure heart.
The result of those led astray is that Jesus will finish His work even in those left behind at the rapture event as God will scourge every child received. ( See Hebrews 12th chapter with 1 Corinthians 3:10-23)
So as the foolish virgins that were at the market getting oil in their lamps.. will be able to shine, alas but too late.. and the prodigal son will return... albeit he lost his first inheritance due to wild living.. but still called a son... but both will be weeping and gnashing of teeth over their loss so that God has to wipe the tears from their eyes of those that came out of the great tribulation.
John 10:1Verily, verily, I say unto you, He that entereth not by the door into the sheepfold, but climbeth up some other way, the same is a thief and a robber. ..... 4And when he putteth forth his own sheep, he goeth before them, and the sheep follow him: for they know his voice. 5And a stranger will they not follow, but will flee from him: for they know not the voice of strangers. 6This parable spake Jesus unto them: but they understood not what things they were which he spake unto them. 7Then said Jesus unto them again, Verily, verily, I say unto you, I am the door of the sheep. 8All that ever came before me are thieves and robbers: but the sheep did not hear them.....
So take note of the following verses of how Jesus will keep His promise even for those led astray by following a stranger's voice that shall be left behind at the rapture event.
John 10: 14I am the good shepherd, and know my sheep, and am known of mine. 15As the Father knoweth me, even so know I the Father: and I lay down my life for the sheep. 16And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd.
So the call is to be watching and ready as we trust Him to keep us from falling and to present us faultless.
Colossians 1:21And you, that were sometime alienated and enemies in your mind by wicked works, yet now hath he reconciled 22In the body of his flesh through death, to present you holy and unblameable and unreproveable in his sight: 23If ye continue in the faith grounded and settled, and be not moved away from the hope of the gospel, which ye have heard, and which was preached to every creature which is under heaven; whereof I Paul am made a minister;
Jude 1:24Now unto him that is able to keep you from falling, and to present you faultless before the presence of his glory with exceeding joy, 25To the only wise God our Saviour, be glory and majesty, dominion and power, both now and ever. Amen.
