Here is a poster–picture that kind of tells the story of missions and church work. But as Trent says it would be better if it read we fight and we give.
Since you are not going to the mission field what are you doing to give extra. It ought to be that it costs us as much to stay as it does them to go.
You have a church staff and missionaries doing the work of God but they can never take your place so get in and got to serving. Take the gospel message to others and support those that do. If God gave you a job that makes more money then be a bigger giver.
Are you involved?
