I didn't ignore "and shall never perish" in John 10:28. I addressed it by quoting that a lost sheep can perish according to Matthew 18:10-14. I explained how.
Once eternal life has been given and one is immortal it is
then that they can never perish. It's after the resurrection. The Bible is conclusive about this.
Luke 20:36
36and
they can no longer die; for they are like the angels. They are God’s children,
since they are children of the resurrection.
1 Corinthians 15:53,54
53For the perishable must be clothed with the imperishable,
and the mortal with immortality.
54When the perishable has been clothed with the imperishable and the mortal with immortality, then the saying that is written will come to pass: “Death has been swallowed up in victory.”
Revelation 21:3,4
3And I heard a loud voice from the throne saying:
“Behold, the dwelling place of God is with man,
and He will dwell with them.
They will be His people,
and God Himself will be with them as their God.
4‘He will wipe away every tear from their eyes,’
and
there will be no more death
or mourning or crying or pain,
for the former things have passed away.”
I think I understand why you are rejecting what the Bible says about this. If you accept what I am showing you then there will be a chain reaction of many your false doctrines you'll have to come to terms with.
