If you are in the middle of a war, no bibles, churches, and struggling to find sustenance, what will you do? The Bible is full of the various ways He communicates with His people; the only things I have not experienced yet are open (wide awake) visions and full conversations. Don’t you want Him to speak within you?
He may have called you there, but that does not mean you were to stay. He knows the comfort you desire in ritual and tradition, but He will break you of this so you can turn to Him alone. Better to take the lumps now, willingly, than being shocked later. And that goes for all of those comfortable in any religion.
World peace is a human concept; there will be no true peace until the rule of man is destroyed. Any peace man comes up with will be short-lived due to the nature of man. See, Daniel, Ezekiel, Isaiah, Jeremiah, Revelation, and the books of Evangel.
Jesus is my peace, just as He said to the disciples. As long as His Spirit dwells within me and I obey Him, I have nothing to worry about.
