The context around this..whatever it means..
So you do admit then you have no idea what Jesus meant when He said 'he who endureth to end will be saved'
Jesus is talking about salvation because when one reads the whole counsel of God we see that NOT abiding in Christ is how one is rejected and cast in to hell.
Some do not abide in Him their entire lives and fall away becoming deceived in to following doctrines of devils and as a result they who were once born again in the end are rejected and spend eternity being tormented in hell with satan and his demons:
*Warnings and Notices concerning the times we live in and the coming end of this age – PAY ATTENTION!
Matthew 24:4,5
And Jesus answered and said unto them,
Take heed that no man deceive you.
For many shall come in My Name, saying, I am Christ; and shall deceive many.
*Many includes those claiming "I am anointed to speak for God" that are deceiving many (false teachers)
1 Timothy 4:1,2
Now the Spirit speaks expressly, that
in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils;
Speaking lies in hypocrisy; having their conscience seared with a hot iron
("depart from the faith" is not referring to sinners in the world who never came to faith in the first place)
1 Timothy 6:3-5 (see Luke 11:23 and 2 Peter 3:2)
If any man teach otherwise, and consent not to wholesome words, even the words of our Lord Jesus Christ, and to the doctrine which is according to godliness (holiness); (Doctrine of Christ, aka Doctrine of the Apostles)
He is proud, knowing nothing, but doting about questions and strifes of words, whereof comes envy, strife, railings, evil thoughts… Perverse disputings of
men of corrupt minds, and destitute of the truth, supposing that gain is godliness: from such withdraw thyself.
2 Timothy 4:3,4
For
the time will come when they will not endure sound doctrine (teaching); but after their own lusts shall they heap to themselves teachers, having itching ears;
And they shall turn away their ears from the truth, and shall be turned unto fables.
2 Peter 2:1-3
But there were false prophets also among the people, even as there shall be false teachers among you, who privily shall bring in damnable heresies, even denying (contradicting, Not agreeing with) the Lord that bought them, and bring upon themselves swift destruction.
And many shall follow their pernicious ways; by reason of whom the way of truth shall be evil spoken of.
And
through covetousness (idolatry) shall they with feigned words make merchandise of you: whose judgment now of a long time lingers not, and their damnation slumbers not.
Jude 1:4
For there are certain men crept in unawares, who were before of old ordained to this condemnation, ungodly men,
turning the grace of our God into lasciviousness (no self control, living after the flesh), and denying (contradicting, opposing Jesus’ teachings) the only Lord God, and our Lord Jesus Christ. (referring to false teachers and false brethren - see Matthew 13:24-30)
Jude 1:17-21
Remember the words which were spoken before of the apostles of our Lord Jesus Christ;
How that they told you there should be mockers in the last time, who should walk after their own ungodly lusts.
These are those who separate themselves, sensual, having not the Spirit.
But you, beloved, building up yourselves on your most holy faith, praying in the Holy Ghost,
Keep yourselves in the love of God, looking for the mercy of our Lord Jesus Christ unto eternal life.
("those who separate themselves" is not referring to sinners in the world who were never joined unto the Lord in the first place)
Matthew 24:3-13
What shall be the sign of thy coming, and of the end of the world?
And Jesus answered and said unto them,
Take heed that no man deceive you.
For many shall come in my name, saying, I am Christ (including saying “I am anointed”); and shall deceive many.
And you shall hear of wars and rumors of wars: see that you be not troubled: for all these things must come to pass, but the end is not yet.
For nation shall rise against nation (ethnic group vs ethnic group), and kingdom against kingdom: and there shall be famines, and pestilences, and earthquakes, in many different places.
All these are the beginning of sorrows.
Then shall they deliver you up to be afflicted, and shall kill you: and ye shall be hated of all nations for my name's sake.
And then shall many be offended, and shall betray one another, and shall hate one another.
And
many false prophets shall rise, and shall deceive many.
And because iniquity shall abound, the love of many shall wax cold. (See 1 John 5:3 AND 2 John 1:6)
But he that shall endure unto the end, the same shall be saved.
Acts 20:27-30
For I have not shunned to declare unto you all the counsel of God.
Take heed therefore unto yourselves, and to all the flock, over which the Holy Ghost hath made you overseers, to feed the church of God, which he hath purchased with his own blood.
For I know this, that
after my departing shall grievous wolves enter in among you, not sparing the flock.
Also of your own selves shall men arise, speaking perverse things, to draw away disciples after them.
