The Urantia Book...

The great God makes direct contact with mortal man and gives a part of his infinite and eternal and incomprehensible self to live and dwell within him. God has embarked upon the eternal adventure with man. If you yield to the leadings of the spiritual forces in you and around you, you cannot fail to attain the high destiny established by a loving God as the universe goal of his ascendant creatures from the evolutionary worlds of space.

The book says that a person ultimately is destined to fuse with his or her divine fragment and become one inseparable entity with it, if the person chooses to accept the Adjuster's leadings and become self-identified with it. The act of fusion is the moment when a human personality has successfully and unalterably won eternal life, described as typically taking place in the afterlife, but also a possibility during earthly life. The result during human life is a "fusion flash," with the material body consumed in a fiery light and the soul "translated" to the afterlife. The Hebrew prophet Elija being taken to heaven without death in "chariots of fire" is said to be a rare example in recorded history of a person who attained fusion.

Once fused with his or her fragment of God, a person continues as an ascending citizen in the universe and travels through numerous worlds on a long, adventurous pilgrimage of growth and learning that eventually leads to God and residence on Paradise. Mortals who reach this stage are called "finaliters." The book goes on to discuss the potential destinies of these "glorified mortals."
The Urantia Book places much emphasis on the idea that all individuals have the same opportunity to know God, and it says nothing can hinder a human being's spiritual progression if he or she is motivated to be spirit led.

The book regards human life on earth as a "short and intense test," and "is not so much a probation as an education"and the afterlife as a continuation of training that begins in material life. The "religion of Jesus" is considered to be practiced by way of loving God the Father with a person's whole being, thereby learning to love each person the way Jesus loves people; that is, recognizing others as brothers and sisters and being of unselfish service to them.
