You don't need to apologize, Rev. We can learn from each other.Uh no sorry it is not simply second death. I think you need to study what spiritual death actually is.
I believe that the second death is the lake of fire. I believe this because Revelation 20 states "Then death and Hades were thrown into the lake of fire This is the second death, the lake of fire" and this is repeated in 21 with "but for the cowardly and unbelieving and abominable and murderers and immoral persons and sorcerers and idolaters and all liars, their part will be in the lake that burns with fire and brimstone, which is the second death."
Maybe you are talking about another "second death"? Which verse are you thinking of?
Keeping in mind that I take Scripture more seriously than I do people's traditions, I am going to ask you. Since you are a Reverend and I take it pastor a church I have no doubt you are in Scripture on a daily basis.
What verse are you looking towards when you explain to your congregation how spiritually-alive people experience a spiritual-death? If you have a link to a time you are teaching this to your congregation I would be very interested.
