We know how to do things and what the proper way to respond is. Living in community is a sure-fire way to be transformed. You have heard the studies that have found that one of the major reasons missionaries leave the field is that they can not get along with other missionaries. We can only truly know ourselves by knowing others and I would also say that we can only truly know God by knowing others. Every person is created in the image of God and as Paul so visually reminds us, it is together, in community that we become the body of Christ.
Most missions organizations send people out in teams now.
You will be transformed by your teammates. It is in community that you are going to faced with the challenge of being transformed into Christ's likeness or to let you sinful nature rule. You will be hurt, you will get angry, and you will be faced with choices to put the other first or to put yourself first. Many of you can think of difficult times you have been through and how in the pain you were transformed more into Christ's image. Our deepest desire for God is often found in suffering.
