My dad once told me that we travel to meet people, and in that way to be influenced by them. If we aren't changed by the people around us, then I don't think that we can truly be who God wants us to be. The greatest men and women I have ever met, were people of different faiths. Their talents and passions were rich and diverse, and they have made me who I am today. I haven't met a single person who hasn't in one way or another shaped the mountain that I am becoming.
I guess really what I am trying to say, is that the port city of eternity isn't Jerusalem itself, but the people that we come in contact with day by day.
So change their lives, let them change yours, and become a mountain.
