“God's life imparted to us,” is (to me) “God's Love imparted to us.”
I believe in God. If I stripped all human ideologies out of the equation, all I would have to do is look at the stars in the universe, and recognize that they did NOT come into being on their own. The universe is orderly, and the laws of physics demand that it be so.
Our universe, or galaxy, is only one of billions. God says the worlds were greater than the grains of sand on all the beaches of the world. I believe it. The photos we have access to concerning space tell us that we are not alone, and we are here because we have a purpose. We are lucky if we find that purpose in this life. But that doesn't mean we should waste the life in idle pursuits. There is so much to learn, and really, when push comes to shove, the only thing that "goes with us" into the Afterlife is our intelligence.
I agree with most of what you wrote. I distinguish everlasting (without end) from eternal (without beginning or end). That might just be me.
God's life in us is literally the Holy Spirit taking up residence in us as His temple. That is when we receive eternal life.
