111:3.1
The mistakes of mortal mind and the errors of human conduct may markedly delay the evolution of the soul, although they cannot inhibit such a morontia phenomenon when once it has been initiated by the indwelling Adjuster with the consent of the creature will. But at any time prior to mortal death this same material and human will is empowered to rescind such a choice and to reject survival. Even after survival the ascending mortal still retains this prerogative of choosing to reject eternal life; at any time before fusion with the Adjuster the evolving and ascending creature can choose to forsake the will of the Paradise Father. Fusion with the Adjuster signalizes the fact that the ascending mortal has eternally and unreservedly chosen to do the Father’s will.
