When our hands become His hands we let others see the cross. When we work together, we become the visible body of Christ in this world for people to see and hear and touch and know.
I heard once that while one person might read a Bible, ten will read the Christian. They will watch your interactions, your reactions, your responses. What they hope to see is not perfection but authenticity. They want to know that you really believe what you preach and that your belief isn’t confined to your head but reaches through your heart to your own hands and feet.
And the best representation of Jesus in the world is not when we act solo but when we serve in context of community and fellowship. They want to know Jesus when they see how much we love and serve each other and by how much we love and serve them.
