Earthly immortality is for the purpose of extending life until the Holy Spirit Baptism with Fire is received, and its testing and proving completed. The next scheduled event beyond is translation into glorified bodies, with all others who have also made themselves ready. In this Age, there are only a few more years of opportunity. In the subsequent cycle of ages, thousands of years will pass before the next wave of glorification. In the meantime, the earth plane manifestation of immortality is the material equivalent of that on the spiritual plane.
Earthly immortality develops into glorified immortality and removal of earth plane limitations.
Holy Spirit Baptism with Fire is also for the purpose of bringing about or accelerating a sinless living, through removal of all temptation. The Holy Spirit baptism event with Fire opens the door to the 100-fold estate. The 100-fold estate participants will manifest God on earth. First, there is the necessary testing and proving of faithfulness to this trust of empowerment and release. Then one has to carefully continue in it until eventual change into a deathless glorified body at the Lord's scheduled time.
