God created a beautiful outside world for Adam and Eve to live in, but their interior world was not created completely. The missing piece for completion of inside world is Jesus. The creation of the inside world will be wholly complete only when Jesus is revealed and His very own image is formed in it.
Even if Adam and Eve had not sinned, Jesus had to be revealed and formed in order for the interior world to be completed.
Sin has destroyed both the outside world and inside world. Sin hastened the completion of the internal world by revealing Jesus. God’s original plan was Revelation and formation of Jesus and then completion of inside world was never disturbed by man’s sin. Just like in 7 days God created the outside world, God had some days to create the inside world. As part of the days of creation of inside world, there was one day for revealing His son Jesus and the other day for formation in the image of Jesus. Sin disturbed the day order in which Jesus was revealed but never disturbed the original plan of completion of inside world.
Adam and Eve were denied the opportunity to eat from the Tree of Life (after the fall), but we can find the fruits of the Tree of Life in Jesus, which we can consume and thrive.
In the internal world, Jesus the master craftsman is revealed. Jesus entered our inside world and began beautifying it as part of the completion of the inside world.
God uses the outside world as a test environment for evaluating the quality of nature and the image of Jesus that has been produced in us.
The creation of the internal world is completed by a person who bears the image of Jesus. He begins the process of restoring the outside world and redeeming creation.
Once the inside world is completed, God will find his new Adam and Eve in the nature of Jesus to rule His Kingdom.
