Jesus talks about stones. Jesus refers to himself as the stone the builders rejected which became the cornerstone, the stone which supports the entire building. He calls Simon the rock on which his church is built and renames him Peter, the rock. He tells stories about people who build their houses on sand instead of on stone. Houses built on sand crumble easily and fall apart.
Houses building on stone are stronger, firmer, and more trustworthy.
Stones, rocks, building blocks and stumbling blocks. They surround us on all sides. We all have stones, big, small. River stones, crystals, gem stones. We have stones of pride, stones of grief, stones of anger, stones of guilt.
