There are two kinds of mosaics, commercial & artistic. Commercial mosaics use cookie cutter tiles, all the same– no rough edges or broken pieces. You see these in ordinary bathroom floors. Artistic mosaics are different. They are hand-made from broken fragments of tile or glass that are diverse in color, shape, and texture. Those broken pieces fit exactly into artist’s vision. The church is artistic mosaic, not a commercial one.
In the mosaic of a church, all the pieces are broken. None of us was placed into this work of art because we were whole. In Ephesians 2, Paul opens by saying each of us was dead in our sins, broken in our trespasses. But, God who is rich in mercy, picked us up, cleaned us off and placed us into His mosaic– on purpose! Our only qualification for belonging to this mosaic was that we were broken in sin and we needed the grace & vision of an Artist.
