This design was inspired by Romans 15:13 - "May the God of hope fill you with all joy and peace as you trust in him, so that you may overflow with hope by the power of the Holy Spirit."
Paul is putting hope, joy, peace, trust and power of the Spirit all together at once. As I mulled over this text, I was confounded as to how to incorporate this prayer into today's context. Then it struck me, Paul was speaking of joy and peace as ingredients that together would become hope. So I went with a metaphor. In the metaphor, we are lemons, often embittered by the world, we may not be the most pleasant company, but once we're squeezed out of our comfort zones, mixed (by the Spirit) with water (peace) and sugar (joy), we can pour out God's refreshing lemonade (hope) into the world.
