Eternal life

John 3:16 promises us eternal life.  That scripture  tells us that God loves us and wants to restore us to Him.
   "For God SO LOVED the world, that HE GAVE His only begotten son. (Begotten in Greek 'monogenes' means unique and the ONLY ONE of his kind) that who ever believes in Him won't perish (die an eternal death away from God). But will have everlasting life. (Life out of the body and in the spirit in the heavens with God.)
Isaiah told us about the same thing in Isaiah 26:19
"But your dead will live,  their bodies will rise, you who dwell in the dust (who have passed away ) wake up and shout for joy!  Your dew is like the dew of the morning,  the earth will give birth to her dead." He is talking to their spiritual selves.  We are spiritual beings who live in a shell like peanuts in a peanut shell.  Matthew 27:50 gives us an example. "and when Jesus cried out again in a loud voice, He gave up His spirit.  (His real self, his spiritual being, left his body.)
Verse 51"the earth shook and the rocks split. The tombs broke open, and the bodies of many holy people who had died were raised to life...They appeared to many people.  Isaiah had prophesied thousands of years before. Now, 1 thessalonians 4:16-17 tell us that all of us who believe will be in heaven with God, those who have died and those who are present.  Hallelujah!
