When Jesus told the story of the two types of builder, and said that the wise man builds on rock (Matthew 7:24-27), He was setting the scene for His promise that He would build His House (the church) on Rock (Matthew 16:18) - a solid, secure and unshakeable foundation. So what does that mean for us in practical terms today?  How is the church to be built? What are the essential foundations?  And how can we play our part in what’s being built?…
