If they should fail, such would prove that God is not all-powerful.

It would also prove that his promises are not sure; whereas the Scriptures declare: "All the promises of God, whatever their number, have their confirmation in him; and for this reason through him also our 'Amen' acknowledges their truth and promotes the glory of God through our faith.

But he who is making us as well as you stedfast through union with the anointed one, and has anointed us, is God, and he has also set his seal upon us, and has put his spirit into our hearts as a pledge and foretaste of future blessing."-- 2 Corinthians 1:20-22, _Weymouth_.
[543]Jesus arose from the dead and ascended on high.

The fact of his resurrection is a guarantee that all men shall have an opportunity for life.

If there is to be no restoration of the human race, then the resurrection of Jesus and the awakening of others from the dead are meaningless and for no purpose.
