If we believe the Bible, we will have to believe the doctrine of restoration.
Jehovah has said: "My word that goeth forth out of my mouth ...

shall not return unto me void, but it shall accomplish that which I please and it shall prosper in the thing whereto I sent it" .-- Isaiah 55:11.
[538]If there is to be no restoration of man to his original state and no opportunity for him to be so restored, then the manifestation of divine justice against Adam amounts to nothing more than God's destroying the work of his own hands and admitting he was and is unable to people the earth with a perfect race.

If we believe in his omnipotence, we must believe that he will accomplish his design.

Having made the promise at the time of the sentence of man that the great enemy should ultimately perish, we may take this as one truth upon which to hang a hope that something better is to come in the future.
[539]If there is to be no restoration of mankind to original perfection, then God's promise made to Abraham is meaningless and must fail, because the express purpose of that promise is the blessing of all the families of the earth; and that blessing is life.

(Genesis 12:3; 22:18; 28:14; Romans 6:23) Not only did Jehovah make this promise to Abraham, but he bound the promise with his oath; and by these two things (his word and his oath, both of which are unchangeable) it is impossible for the promise to fail; but in due time it must be carried out .-- Hebrews 6:17,18.
[540]Beyond question, the Scriptures show that Jesus, who in his prehuman existence was the Logos, left the heavenly courts, his life being transferred from spirit to human plane, took upon him the nature and form of man, and became Jesus for the very purpose of saving the people from their sins.
