Acts 4:11

This is the ‘stone which was rejected by you builders, which has become the chief cornerstone. '

1. The corner stone we talk about today is a stone near one front corner of a building to identify when the building was built.

2. In the first century the corner stone was a small stone not useful for building a large building, so it was tossed aside.

3. To construct an archway or gate, they would build 2 pillars. Then they would start curving from each pillar to meet at the center top.

4. One small stone was needed to "wedge" in, bind it all together without mortar.

5. This small stone used at the top of the arch was called the chief corner stone.
