With Christianity becoming less popular in the U.S. You can only make the assumption that foreign missions is taking a hit as well.
But according to pg 14-15 of our material, with the decline in the average americans belief in absolute truth (only 33% in 2001) there seems to be an incline in the flourishing of other religions here in America, which actually brings the mission field to us here in the states. I think this actually might set a fire in the American Christian and might give them a passion for foreign ministry, as they are becoming more exposed to foreign religions and foreign cultures in their hometowns. Sometimes christians need to be shaken up a bit in order for them to wake up. Perhaps the introduction of mosques and temples in their communities will do that.
