My church recently had a service where a portion was given over to “cardboard testimonies.” You may have seen these, either in person or on video. The participants write something they’ve struggled with (like an addiction, infertility, or abuse) on one side of a piece of cardboard and hold it as they silently walk across the front of the room. After a few seconds, they flip the cardboard to reveal how God has moved in the situation. They tell first-hand accounts of finding love, healing, peace, and forgiveness.

The scene was one of the most moving things I’ve ever witnessed. I don’t think there was a dry eye in the room filled with hundreds of people.

What made it so powerful was their transparency. Each one was revealing a side of themselves that many did not know. They were reaching back into their pasts to demonstrate God’s power in their lives.

No one preached a fire-and-brimstone message that day,  but lives were undoubtedly changed.

I think it’s a good example of what Paul was talking about in 2 Corinthians when he wrote

“This letter is not written with ink, but with the Spirit of the living God. It is not written on stone tablets but on human hearts.”

When God does a work in our lives, it is written on our hearts. We don’t have to preach condemnation to those around us to get them to see their need to change. We just have to open up our hearts and show them what God has done in us.

Who do you need to share your heart with today?
