I have been thinking about the Gospel and the kingdom of heaven lately. I know it surprised me too. Jesus talks about the kingdom of heaven some 33 times so I think it is kind of important. One commentary defines the kingdom of heaven as “the rule which God exercises through the person, work, and teachings of Jesus.” I think that is a pretty good definition but to go a little further Edward Schillebeekx (no I did not make that up) says the kingdom of heaven is “a process, a course of events, whereby God begins to govern or to act as king or Lord, an action, therefore, by which God manifests his being-God in the world of men.” I think that one is pretty good too. But I would simplify it a little and say the Kingdom of Heaven is God ruling now.
Have you ever heard the expression that some people are too heavenly minded for their own earthly good? I have and to be honest that is how we should live. The problem is that what is meant by that is some people are only looking forward to the after-death part of heaven and not the here and now part. I am not talking about heaven on earth as in everything is perfect but God ruling here and now in us. Jesus coming to earth, living, dying, and being raised again was an invasion. I mean think about it, Jesus came to earth to bring the kingdom of heaven here. He came to bring people out of sin and death and back into God’s kingdom.
We live in this weird now but not yet place of belonging to Heaven but still residing on earth. The kingdom of heaven lives in us and we carry around the kingdom of heaven everywhere we go. The Gospel message is that we can live in that reality of heaven now. Yes, one day when we die we will move there so to speak but we have it now. Right now, at work, at home, even in the car you have the kingdom of heaven because as a Christian you have submitted yourself to Gods rule.
As believers in the resurrected Christ, we live in the reality of this. This is why Peter writes to people and calls them sojourners or pilgrims. We should live heavenly minded but we should understand that it is a destination and position we currently hold.
Just a thought,
