There are two senses in which I want to ask this question. The first is physically where is the Cross? Do you have one on display somewhere? If so is it somewhere focal, or is it in the periphery?
I have been in a few different Churches, and I know that they pretty much always have something on display. In a Church building it might be ornate stained glass windows, or engraved Bible verses on the walls. In a rented place its more likely to be handmade banners hung up somewhere. I have never been in a Church where there was nothing (although Im sure some Churches do go this way). So if youre going to display something, it should probably be the Cross first and foremost. A picture of a rainbow is lovely, but the rainbow was a promise pointing towards the Cross. A Bible verse is great, but the whole Bible is about the Cross, so why not that.
The second sense in which I ask is where is the Cross in the actual service? Is it in the welcome when you invite people to take a seat and thank them for coming? Is it in the conclusion where you invite people to stay and share tea and coffee with you? How about all of the many parts in between?
I sincerely hope that the Cross is a major (or better, the major) focus of the worship, and of the sermon. But what about the other parts of the service? How can we best display Gods grace through the Cross in the way we do Church?
