The bringing of humans to full perfection in body and mind, however, will be a gradual process, requiring the application of Jesus’ atoning sacrifice and obedience to the direction of the Kingdom administration. What will take place might be compared to rehabilitating a disabled person under the guidance of a skilled therapist. During the course of his training the disabled person may make many mistakes but eventually he may come to the point where he is able to live a useful life without having to depend on others. The progress he makes depends on his response to the help given.

While growing to perfection, humans will still be committing sins unintentionally. But by repenting and asking for forgiveness of God through their High Priest Jesus Christ, they will be forgiven and will continue to receive help in overcoming their weaknesses. Depicting the divine provisions for life and healing, Revelation 22:1, 2 speaks of “a river of water of life, clear as crystal, flowing out from the throne of God and of the Lamb down the middle of its broad way. And on this side of the river and on that side there were trees of life producing twelve crops of fruit, yielding their fruits each month. And the leaves of the trees were for the curing of the nations.”
