I have cited 3 Biblical examples where sinners were dead but still alive. Death does not mean cease to exist. How about another?Sorry, you don't get to make up your own definitions. Death means the cessation of life. Here is Webster's definition.
a permanent cessation of all vital (see VITAL sense 2a) functions : the end of life
No one is alive but dead in a literal sense. That is only possible figuratively, such a metaphor. To be alive and dead literally at the same time is a logical contradiction and not possible. A basic Law of logic states that two opposing things cannot both be true at the same time. Thus someone who is said to be dead, is dead, unless is it used in a metaphorical sense.
You know, one of the most troubling things I find is how Christians will redefine words to fit what they believe rather than changing what they believe to fit what is stated.
Ephesians 2:1 (NKJV)
1 And you He made alive, who were dead in trespasses and sins,
Dead and alive!
