Genesis 3:8; 2 Corinthians 5:17
There was a time in God's special garden in Eden that man and woman took walks with God in the cool of the evening. Apparently, God drew near in the form of a human body in order to enjoy this garden time with them. The man and woman's sin ruined all of that, corrupting human nature itself. Now the human life would be marked by Death in many forms of experience.
At just the right time, God took human form again, but in a very unique way. God united his own being to the corrupt human being in the man, Jesus. By sacrificing this human life for our sins, God renewed human nature in Jesus Christ. Now, we have God's promise that in Jesus we will someday enjoy the fullness of that new humanity. Someday, we will take walks with God again in his special garden.
Naturally, we all wish we could live in a place like the Garden of Eden. This is at the heart of much of our progress and civilization. Still, crime rates and constant wars around the world remind us that modern civilization is far from Eden. Jesus teaches his disciples how to live the life of Eden now, even while we are still so far away.
