Where did the warning that you will die come from originally?
The warning originated as God's first admonition to Adam and Eve in the garden, that the day they ate they should surely die. That original warning has not changed: if you live after the flesh, you will die, but if through the Spirit you mortify the deeds of the body, you shall live.
Les teaches that Romans 8:12-13 echoes the first admonition given to Adam and Eve in the garden: the day they ate, they should surely die, and that warning has not changed. The text says we are debtors not to the flesh, to live after the flesh, for if you live after the flesh you will die. Les explains the Christian life does involve discipline, but it is not merely giving things up; the things once loved are hated and vice versa, a change of appetites. Through the Spirit, mortifying the deeds of the body brings life.
But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die.
