Hi Bill ~
A few thoughts......
One may just as well be a bacteria or a plant life if not hearing, obeying, listening, seeking, anticipating, following, discerning, praising and worshiping Christ, Who bears the fruit of love, joy, peace, kindness, goodness, gentleness, faithfulness, patience and endurance.
All that is, is OF God ~
You ask what is life. God removes His Spirit, and we die.
Physical death is as sleep (unconscious) John 11:11 Matt 9 : 24
Spiritual death is as slumber (strong delusion)
Both physical and spiritual death is overcome by the Spirit of Christ and God The Father.
God neither slumbers ( is not deceived) nor sleeps (is not unconscious).
God is an Alien to one who is spiritually not yet alive. eg. Adolf Hitler professed Jesus Christ as his Savior. The fruit of Hitler was murder, lust, pride and avarice. The fruit of Saul,
"the chief of all sinners." was the persecution, victimisation and murder of the children of God.
Saul was as spiritually dead, before he was given Spiritual Life of the crucified and Resurrected Jesus Christ, that made him, to be Paul.
Christ in you, brings life. Unrepentant slavery to sin, brings death.
To become as Christ IS, is not given to any plant, animal, angel or demon.
Is God living you ask. God is the God OF the living. God IS Life. It is the same as God not being A Spirit ~ God IS Spirit. God IS LIFE>
Hope there is something that makes sense to you....
Blessings
