The Gospel of Mark can read read as a sermon... performed if you will, in about 45 min. This gives credence to the notion that it came by way of writing down Peter's oration of his personal testimony of Jesus by John Mark. The language and tone of the text has immediacy. It is action oriented. It has dramatic flare unlike the other gospels which makes sense if you are hearing versus reading the words. This gospel is probably one of the best records of what first century preaching sounded like, and perhaps the next time you read mark, you hear it differently.
In the times of King David, the Philistines had the advantage. The reason? Technology. Iron, and mastery of its use in warfare made one’s culture gain superiority. Was David was on the run from Saul and gained favor with the Philistines, he was given a wife and a city. It’s possible he brought the technology of iron with him. Once these secrets and skills were in the hands of Israel, the Philistines domination rapidly declined.
When we’ve found Love to be the answer, we have to master the technologies of our cultures to affect them for the powers of good.
