The following is not an original, but the exact quote and the author credited for the idea escapes me.
Christians and Jews have been fighting for centuries. The Jews believe Jesus Christ was a great person, but was not the Messiah. They believe the Messiah will come someday. The Christians believe Jesus Christ was the Messiah and will come again someday.
How about focusing on agreements versus disagreements, wait for the Messiah to come someday, and ask Him if He has been here before?
This is a roadsign for our journey to a joyful pursuit of happiness.
