Though not stated, it was a question on the idea of 'Eternal Security'-whether or not a Christian could have his name blotted out of the Lamb's book of Life. In the book of Revelation there is mention of this, and, as I said, I got it wrong. My point was that from God's perspective, He knew who would or not be saved, as He was the one doing the saving. So talk of 'blotting out a name' was poetic language, not literal. When I got home I dug in to find the reference:
"4But you have a few there in Sardis who have kept their clothes unstained, so they will walk with me and will wear white clothes, because they are worthy.
5Those who win the victory will be dressed in white clothes like them. And I will not erase their names from the book of life, but I will say they belong to me before my Father and before his angels.
6Everyone who has ears should listen to what the Spirit says to the churches." Revelation 3:4-6
God was letting the saints in Sardis who had kept their clothes unstained know that they would walk with Him. He was assuring their security; they need not fear losing their salvation.
But note that Jesus was talking to the righteous in Sardis. He makes no such promise to those elements of the Sardis church who had not lived righteously. He didn't need to blot out their names from the book because they had never been written in.
If Christ caught up His church today, I would love it if my church were represented 100%...as far as I know we would be. But God sees hearts and knows who is or isn't saved. Sardis had "just a few". Hhmmmm.
