Hi, and appreciate your reply and comments! If one professes to be in the faith and eventually permanently ceases from it, this manifests it was a false profession they left, not a true one, for true professions means one is reborn, has been given an additional but new nature, has the Spirit indwelling, using the Life of Christ in us (Col 3:4); and the Father's "work" to keep us "desiring" and "doing" His "good pleasure."
I see Heb 6:1, 2 describing going to the Gospel of Christ (rebirth) from the practice of the Law, e.g. "baptisms," here refer to ritualistic practices using the name "washings" to be synonymous with "baptisms" (e.g.
Mar7:4;
Heb 9:10).
If you're referring to "laying on of hands" I agree, the gifts of the Spirit in the apostolic capacity ceased with the death of the last apostle to die, John. But in this passage it's in the sense of the Old Covenant's usage of Priests and authoritative people of God, mostly in sacrificial related usages of the Law, e.g. the transferring of the sins of the people to an animal about to be sacrificed (Leviticus 16:21; 24:14; Numbers 8:12). This was written to the Hebrews Christians to inform them they could no longer practice it, Christ being the final sacrifice.
If by "full glorification" you mean new body and no more "old man" (sin nature), this is true, as rebirth presently and forever secures our salvation.
Matthew 24, esp. verse 12 is mostly in reference to "false professors" (v 11).
If one fails to overcome it's only because God was never with them, because it requires Him to be an "overcomer."
I believe the warnings in the messages to the Asian Churches (and through the entirety of the NT) are admonishments for the purpose of identifying a believer, because true believers will not present a false profession, and many do. It's not as any name could be actually "blotted out" (
Rev 3:5), because there will never be a need for the blotting, seeing that God has always known who will be saved.
