The need to work together?

Here is an interesting issue. I have heard from too many places recently the need for Churches, leaders, and youth leaders to be physically seen to be working together, but is this really necessary? do people outside of Church really care? does it really achieve anything? And is it what was meant in the Bible when the issue of one body was mentioned? I would suggest that a recognition of who we all are, and all our diferent gifts, and the ability to be nice and relate to each other is fine. I don't see that there is any atual need for us to physically do things together, becausse we may all be called to wrok with different people, at different times, and do different things, so is it more imortant that we work tother,or be seen to be work tother, or that we follow the calling that God has placed upon us. Support each other, encourage each other, meet together, look after each other, and pray for each other, and let's see what hhappens when we follow the alling by God, and support each other in that.
