Yeah, but you see they concocted a "get-out-of-jail" card even for this one. They will say that those who commit such sins are not (and never were) the elect. LOL!
They also deny that, once saved, you cannot lose you salvation (fall) because God promises that nothing will snatch you out of His hands.
This flies in the face even of +Paul, from whom they claim to get this theology (by revisionist interpretation of Luther's), when he says: "So, if you think you are standing firm, be careful that you don't fall!" [1 Cor 10:12]
Duh! And they say the Lord's Supper is a "symbolic" ritual. Yet +Paul says "Is not the cup of thanksgiving for which we give thanks a participation in the blood of Christ? And is not the bread that we break a participation in the body of Christ?" [1 Cor 10:16-17] Double Duh!
When your children "fall" are they still not your children?.. You pick them up and wash them off.. practically.. You may warn and/or forgive them..
There are no words in any language I know of to be "UNBORN AGAIN" or after being "born" to be "UNborn".. physically or even spiritually.. "You MUST be born again" - Jesus.. Being UNborn is UNscriptural.. And flys in the face of the image..
Witness the "Prodigal son".. The father ached for his sons learning phase.. and missed him still as his son.. Witness also his brother.. and all that "hubris".. I guess you buy some people books(bibles) and they EAT THE PAGES...
Do you think that was a valid promise from God?
