There are many indications that we are indeed in the last days. Here is an interesting extrapolation...
One of the reason God kicked man out of the Garden of Eden was to deny him access to the Tree of Life...
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...
In this situation, God tossed man out and put a guard around the Tree of Life.
Humanity (human scientific technology) is close to a point at which the human life expectancy can be extended dramatically. In fact, just this month in Barcelona, a woman received by operation a transplanted trachea grown from her own stem cells in a lab (source). Her body accepted it without immune-suppressing drugs.
It is thought by many in the scientific community that this is just the beginning and that many organs can be so grown.
Conclusion: Man is trying to circumvent the need for the Tree of Life to achieve immortality.
God will prevent it.
Excellent post.
