I am trying to summerize the bible in a few words. I came up with 5 small paragraphs
1) Out of love, God created the whole cosmos for his children to be born on earth where they can learn to love and prepare themselves to enter the spiritual world where they can be with Him for eternity
2) Unfortunately, Adam and Eve, the first ancestors of humanity, did not follow God's commandment during their growth period and united with Lucifer against God, creating, starting from their family a sinful lineage and hell on earth.
3) From that moment, God grieving to bring back his children to Him worked to prepare a new foundation of faith to receive a new sinless Adam and Eve in order to establish a new lineage completely separated from Satan and through which humanity could be grafted and Heaven on Earth finally established.
4) 2000 years ago, Jesus was born after a long period of preparation as the second Adam in the chosen nation of Israel but he was rejected and crucified before he could create and establish God's sinless family. Satan killed his body with his precious seed but could not take his spirit. Jesus'total obedience and victory on the cross brought spiritual salvation for all humanity.
5) God once again is preparing with Jesus and the Holy Spirit a new foundation of faith to receive a third Adam and establish His lineage on earth separated from the original sin of the first ancestors.
