Ok I think I understand your point a little better. Thanks.
Yes we can because death only comes as a result of sin:
Rom 5:12 Wherefore, as by one man sin entered into the world, and death by sin;
Rom 6:23 For the wages of sin is death;
Rom 7:11 For sin, taking occasion by the commandment, deceived me, and by it slew me.
And because God doesn't create mortal things but he is the God of the living, not of the dead, as our Lord taught us:
Mark 12:27 He is not the God of the dead, but the God of the living: ye therefore do greatly err.
Yes we do because God said exactly that:
Gen 3:22 And the LORD God said, Behold, the man is become as one of us, to know good and evil: and now, lest he put forth his hand, and take also of the tree of life, and eat, and live for ever:
I honestly fail to see the problem here, and of experience, whenever someone unduly struggles with a simple Biblical truth, it's that they're actually aiming at resisting another target behind that surface issue.
