Yes.Man NOT saved is NOT in Christ, and while NOT in Christ, man is dead because Christ is our life (Col 3:4).
A vast majority of preachers teach that to be in Christ, people MUST first ACCEPT the gift of salvation and believe.
So, how can a man ACCEPT & BELIEVE while still spiritually dead?
In the story of the Prodigal Son, he is said to be dead, but still chooses to return to his father's home where he became alive again.
