There is NOTHING in Phil 1:6 speaking of the ‘elimination of actual sinning” NOTHING! What Paul speaks to was their coming completion and fruition in the fellowship of the gospel… from the BEGINNING, which as it transpired, was the work, will and pleasure of God, i.e., chapter 1 verse 5 and chapter 2 verse 13 — context NOT theological pretext!!
As for Heb 9:26 your theology denies this verse claiming Jesus is STILL yet to accomplish this… thus your theology has an incomplete and thereby weak salvation.
And Tit 2:14 simply makes the case I have stated previously… that said requirements were pertinent to those called to His kingly and priestly service, i.e., believers, of whom the higher standard WAS indeed required — of whom much was given (ministry) much was required (fidelity).
And again… 1Pet 2:24 is in the context of Christ’s servants, i.e., believers, and NOT a general requirement that unless fulfilled has one in hell learning such until fit to get into heaven — which IS what you indicate elsewhere. Here is the CONTEXT of verse 24…
1Pet 2:21 For to this you were called, because Christ also suffered for us, leaving us an example, that you should follow His steps:
Adam’s SIN wrought the wholesale imposition of guilt / liability <ἔνοχος> enoxos and thus condemnation to all assigned as being “in Adam”… it was this imposition that God removed in Christ.
Now you guys here may be unique, BUT it has been my experience that universalists claim that… whoever was formerly placed in the first Adam was summarily placed in the last Adam and this was the work of God.
There is a difference between the collective AND THOSE called to serve it — and it is this that you guys seem not to understand.
