Let's be honest. Learning about missions is one thing. Doing it is another thing altogether.
Most people, even Christians from good churches, think that personal involvement in missions for someone living in the western world is limited to praying and giving money. Christians in North America tend to be confused by the consumer mentality of thinking that living out their faith is a spectator sport. Go to church on Sunday, give God a tip in the offering, try to be good, and grow a little bit in love and kindness, and that's it!
