The attainment of immortality is achieved with the fusion with our Adjuster. After the fusion of the immortal morontia soul and the associated Adjuster, all of the experience and all of the values of the one eventually become the possession of the other, so that we two are actually one entity. 
That the way which leads to eternal life is straight and narrow, that the door which leads thereto is likewise narrow so that, of those who seek salvation, few can find entrance through this door. But even if the door to the way of life is narrow, it is wide enough to admit all who sincerely seek to enter, for Jesus is that door.  The life after death is no different in the essentials than the mortal existence.  The morontia soul, being superadjutant, does not retain self-consciousness without the Adjuster when deprived of the material-mind mechanism.  No misbehavior by others can ever jeopardize one’s eternal prospects. 
No personal creature can be coerced into the eternal adventure; the portal of eternity opens only in response to the freewill choice of the freewill sons of the God of free will.  What would a man give in exchange for e.l.? 
Life in the Father’s eternal creation is not an endless rest of idleness and selfish ease but rather a ceaseless progression in grace, truth, and glory.  Eternal life is the endless quest for infinite values. 
All the power which is inherent in Jesus—the endowment of life—and which enabled him to rise from the dead, is the very gift of eternal life which he bestows upon kingdom believers, and which even now makes certain their resurrection from the bonds of natural death.  Eternal life is gained by hearing the gospel of the kingdom and believing in the teaching of sonship with God.  Eternal life is a gift of God.  Every one knowing God as Father and believing in Jesus shall have ternal life. 
Spirit-guided mortals are aware in this life of eternal life; they have the eternal life joys now.  Whosoever believes this truth of the combined nature of the Son shall be endowed with life that is more than age-abiding.  Believers react to this temporal life as if immortality already were within their grasp.
