Is there a sin sacrifice in Trinitarianism?

I reject your interpretation of 1 Tim 6:16.

God CAN die, and he DID die.

Holding immortality here is the idea that you cannot stay dead, not that you cannot die at all.

As Acts tells us, Jesus was the Author of Life whom Death could not hold (not did not—COULD not).

Yes, God possesses immortality, but he can also momentarily set it aside.

And death is also the separation of the soul/spirit from the body. It does not mean cease to exist as the JW heresy teaches.

So yes God the Son did die and the OP is a failure.

Hope this helps !!! @Runningman
