On that day you will realize that I am in my Father, and you are in me, and I am in you. (John 14:20 NIV)
How pleasant was the experience with God sitting down and talking with Adam and Eve in the Garden! The jovial communication, however, was broken when they both sinned in disobedience. God could no longer live in a dirty house so he vacated the premises and forced Adam to fend for himself in a hostile environment. Sin created a great gulf between God and his creation, but he had a plan.
God disguised himself in the person of his Son, Jesus Christ and came to live among mankind. What do you supposed it felt like for Jesus to sit around a campfire and openly discuss the problems of the day with his twelve friends? Was this what God in Christ had always longed for? Did it remind him of his original time in the Garden of Eden?
The disciples spent three years with Jesus, but had no clue that the one walking, talking, and teaching them was God in the flesh. Near the end of his life, Jesus attempted to remove the disguise. He said, "Anyone who has seen me has seen the Father. Don't you believe that I am in the Father, and that the Father is in me? (John 14:9-10 NIV)
There it is -- God disguised in Jesus, His Son. Do you know the Father? You do, if you know and believe in Jesus -- his Son.
