Failure to Live Dangerously

In Richard Adams' book, Watership Down, the author creates a story in which a group of rabbits learn the dangerous truth.  They were given the gift of strong hind legs, their story of creation and speed in a world that will be an 'enemy' to the rabbits.  Their world will always be dangerous.
Most of you are saying, we aren't rabbits (though I sometimes wonder if this analogy might be more on target than we would like).  True, but we, too, live in a world full of dangers for our species, Christians.  Some of us would like to withdraw (clearly not Jesus' intent in John 17), some of us would like to build walls and fortresses (also not the witness of the one we call our leader, Jesus).  But what I think God calls us to do (it is spelled out clearly in Michael Frost's book Exiles) is to thrive in this culture by relying on the skills and gifts given to us by our leader, Jesus.  We are to even "bear much fruit" in this dangerous world.  But how?
David gives us an example of this and I want to rely on only one phrase in David's story from 1 Samuel 17.  That phrase is "The Lord who rescued me from the claws of the lion and the bear will rescue me from this Philistine [Goliath]."  Let's break it down.  David knows he is going into a danger that is impossible for him to defeat ... this is why he must be rescued.  But David does something I see few modern-day Christians do ... he goes into the battle knowing he cannot win in his power.  He must count on the greatest gift his maker has given him ... the might of the maker.  I see this real life example (we often reduce it to 'story') played out every day.  We can't do this because it is dangerous.  We can't spend that money because I can't make the numbers work.  We can't do that ministry because it brings up new liability.  We can't ... we can't ... we can't.  Of course we can't ... because if we could in our own strength then the power of God wouldn't be shown to the world so that our Father in heaven would be glorified!  The point isn't my security ... it is God's glory!  Living the life of a Christian in this world can only be done with the might, the gifts and the power of God.  In the words of an old folk song, "when will they ever learn, when will they ever learn?"  That's my take!  Pastor Randy
