When Jethro said farewell to Moses, he used the Hebrew phrase . . . "lech l'shalom" . . . literally, "Go TO Peace" (Exodus 4:18) . . . . towhich the rabbis added "and he succeeded," going on to return to Egypt and liberate his people. But when David said goodbye to Absalom for what turned out to be the last time, he said, "lech b'shalom" . . . . literally "Go IN Peace" (2Sam.15:9) . . . after which "he died."
We "Go TO Peace" for a life of mission and ministry. We "Go IN Peace" when we find the completeness and wholeness and perfection of death. In life we can only word towards peace, but never be "in peace."
