If you put forth half the effort trying to live like JC as you do taking him out of context you would be a better person for it. Jesus was immediately to bring spiritual peace, to make accessible peace between God and man. Jesus, in His first coming, was not to bring world peace between men. The "sword" is analogous to "Gods word"
Indeed, it is sadly ironic, that the Gospel, which is Good News for absolutely everyone, does not bring peace, but brings a "sword". "When Christianity divides families and produces wars, this is not the fault of Christianity, but of human nature" [broadus, 234]. The "sword" is a result of people rejecting God’s Good News, and turning upon the bearers of His Good News. "Truth provokes opposition, purity excites enmity, and righteousness arouses all the forces of wrong" [spurgeon, 129]. The cause of the strife is not the Gospel itself, but the rejection of the Gospel. Men reject the truth of the Gospel because they desire to continue in their ways of sin. As Jesus summarized elsewhere: "This is the verdict: Light has come into the world, but men loved darkness instead of light because their deeds were evil" (John 3:19).
