What God is preparing us for is to be walking in total dependence on Him for life itself.
We’ve never had an example of what this would look like, especially in this day and age. But by reading about Jesus as our example we can get a good idea: Jesus was so dependent on His Father to be life through Him that His Father could revolve the entire universe around Him.
The Father sent His Son, trained and taught His Son, crucified His Son, lowered His Son, resurrected His Son, and is glorifying His Son, all with the perfect cooperation, dependence and enjoyment of His Son.
Though this was all the Father living His life through Him, Jesus was fully engaged in everything His Father was doing.
The last thing we would call Jesus was passive.
