"What unified them and should unify us is worship, not fellowship."I don't think that I have ever thought about fellowship in the light of diversity. We are all very different and it makes sense that our fellowship with each other will reflect that diversity. Conversely, we bring this diversity with us and somehow find unity when we worship.
It reminded me of a time four years ago during a Sunday morning worship service at church. Ann and I had been attending a few months and liked the church okay. Then, on that one Sunday morning, as I was pouring my heart out in worship ... my eyes closed ... His presence seemed so rich and present ... I opened my eyes and saw people all around me entered into worship. I am not sure that I can communicate how much I identified with those folks at that moment ... it was transcendent ... even though they were so different than me ... that identification in worship was so strong ... it changed me.
A strong message of the kingdom is that we are so different and yet so similar. We are diverse in ethnicity, in language, in intelligence, and in callings ... even our worship expressions are different. Yet, we are so similar. We all experience pain and joy. We all need friends. We all need encouragement. We all need to be loved. This is where worship can make a difference. Worship can unite diverse people because it gives us access into His presence. In His presence those things that separate us fall away and we experience unity.
