So the question is: How do you INHERIT a paid-for debt?
The answer is the debt was not paid for. Adam the sinner could not redeem such life simply because he died. We cannot redeem ourselves simply because we die. That same life still condemned continued along with those that possess it. The possessors of it die, yes, that much is true. But the giver of that very life had to sacrifice that same life faithfully in order to make it possible for that life to be redeemed by the same blood that is common to us all. It did not matter when in time this took place. It only mattered that it did take place to make it possible for us to gain not just life, but eternal life during this last day.
Adam is still alive, then? You say his LIFE is still alive and the people who possess it die. Are you speaking English?
If you possess LIFE you are alive. People cannot "POSSESS" life because it is a chemical process of self-sustained actions at a cellular level. It is not the GHOST or God magic you pretend it is.
REDEEMING Life is another matter. You do not and cannot redeem life. You have to try and determine the VALUE of the life lost.
So, you've even missed the point of that!
The VALUE of life is what gets redeemed and not LIFE itself.
How do you manage to keep all of this straight in your head when it is so jumbled, chaotic and entangled with bent conceptual framework???
Amazing!
