Have you heard the saying that broken crayons still color? It’s true.
It’s also true that God uses broken people to bring out the colors in the world. Those, and not the perfectly whole people, are the ones God favors to work in and to work through.
God uses wounded healers because He is a wounded healer. He still bears the scars from His wounds by which we were healed.
Those marks on His hands and feet are to remind us that we weren’t healed and saved to bask in our deliverance, but to turn around and help others find healing. We have been reconciled through shed blood in order to facilitate a ministry of reconciliation based on the Prince of Peace.
