Do our lives have purpose? How do we know? Does everything we do just accidentally happen to us or do we strive to reach a goal that benefits others or our Creator? Surely our immediate reward is greater when our purpose extends outside ourselves. Certainly our eternal purpose awaits greater rewards. We can blend together for a common good when we include others in our plans. I think God meant it to be that way. Especially for Christians, He intended for us to be one body supporting the other just like our physical bodies do.
