This passage has always been one that has led me to respond, "Really Lord? You can't be serious." But I think Jesus is serious here. Jesus was fully human and fully divine, yet he was still only one man whose earthly ministry lasted less than four years. Yet he has blessed many of us with long life and a clear ministry that can last decades. Not only that, but we can pass our ministries and missions on to the next generation, steadily growing a vast army of workers to do God's will on earth. Time and communal effort multiply miracles.
Isn't it interesting that Jesus says we will do greater things because he is going to the Father, not despite it? I think Jesus needed to go to the Father instead of remaining on earth to give us space and underscore the reality that we need to take full responsibility for every aspect of our lives in him. This is a tough one for all of us. There always seems to be at least a corner of our hearts that we shield from him, keeping it in the dark, away from his blinding light (or so we think). But of course Jesus has all the time in the world and infinite patience. It is we who are slow to learn (see 2 Peter 3:9).
