Never Say Die ?

I posted a short comment today on Facebook (sewer of mindlessness that it is, I post there on occasion), that it was the 50th anniversary of C. S. Lewis' death.

It raised an interesting question: what terminology is correct for such a Christian's death ?

That he was ushered into God's Presence ? He lived in the Lord's Presence.

That He entered God's Kingdom ? He was already a citizen of God's Kingdom.

That he "died" ? He began to live fully.

I didn't find a good term for a saint's death.
