I remember being at a conference where there we hundreds of other churches, from a wide variety of denominations (and non-denominations!) present. Seeing the great sea of people gathered together, the speaker asked: “How many churches are here today?”
The answer: One.
We worshipped together at that conference, but the sad truth is that we wouldn’t have been able to worship together every week on Sunday. For a great variety of reasons, from things like the mode of baptism to exactly what happens at the Lord’s Supper, from how to interpret the book of Revelation and other passages in the Bible to the role of the Holy Spirit and so much more, the history of the church is the history of one group of people not being able to go on worshipping together with another.
Won’t it be a surprise, then, when in heaven we have to worship with those we could not worship with on earth?
Which raises a really, really big question: Why wait?
