John 17:12 - While 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.
Yes, in context Jesus was speaking of the 12 disciples not all who would be born again claiming none of them would ever fall way which we see that some do fall away when we accept the entire counsel of God show in Hos Word not being cherry pickers.
This is ONLY applicable to those that hear His voice and follow the Lord which those who fall away quit doing.
John 10:27-29 - My sheep hear my voice, and I know them, and they follow me:
And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand.
My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand.
No outside third parties (like demons or other people) can force someone out of the Lord's hand, but this is not speaking of people themselves who are fully capable to choosing to depart from the faith as we see in 1 Timothy 4:1,2 and 2 Timothy 4:3,4 and 2 Peter 2:20 to name a few
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)
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 2:20 - For if after they have escaped the pollution of the world through the knowledge of the Lord and Savior Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning.
Some choose to depart from the faith and quit abiding IN Christ which Jesus spoke of in John 15 speaking of those IN Him who do not bare fruit the Father would cut them off.
John 15:2 - 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.
When we get born again we are translated from darkness in to the Kingdom of God's Dear Son (Colossians 1:13) at which point we are IN Christ, so we know Jesus is speaking to and about believers, those who have been born again in John 15
Sorry but God does not force Himself upon people seeing He has given mankind free will meaning salvation is not all up to the Lord which is what the false doctrines of the calvinists claim so if someone decides to depart the Lord does not save them anyway as they reject the Lord and turn away from Him.
Are you going to also tell us God decides who gets saved and who doesn't?
Or that Jesus only went to the Cross for a few people and everyone else is assigned to hell before they were even born?
These are all calvinist doctrines they got from the devil.
You should get a hold of Ephesians 6:10 - Finally, my brethren, be strong IN THE LORD, and in the power of his might.
Those IN THE LORD are not weak and fragile because they submit to the Holy Spirit and let the Holy Spirit live within them
Romans 8:11 - But if the Spirit of him that raised up Jesus from the dead dwell in you, he that raised up Christ from the dead shall also quicken your mortal bodies by his Spirit that dwelleth in you.
Here's a few more thoughts to ponder
Matthew 7:14 - Because strait is the gate, and narrow is the way, which leadeth unto life,
and few there be that find it.
Luke 13:24 -
Strive to enter in at the strait gate: for many, I say unto you, will seek to enter in, and shall not be able.
Jesus did say to strive to enter in, and the way this is done in the New Covenant is to abide IN Christ by submitting our lives to Him as we fight the good fight of faith (
1 Timothy 6:12)
I can do all things through Christ Who strengthen me (
Philippians 4:13), which is how we strive as we fight the good fight of faith by submitting ourselves unto the Holy Spirit allowing Him to make us strong in God's Word
This is not earning our salvation or doing things in our own strength and ability as the unlearned falsely claim, this is being a true son of God by being led by the Holy Spirit (
Romans 8:14) based on God's Word (See
John 16:13, and
John 17:17) to be obedient to the Lord to abide IN Him.
