Nobody escapes being wounded. We all are wounded people, whether physically, emotionally, mentally, or spiritually. The main question is not "How can we hide our wounds?" so we don't have to be embarrassed, but "How can we put our woundedness in the service of others?" When our wounds cease to be a source of shame, and become a source of healing, we have become wounded healers.
Jesus is God's wounded healer: through his wounds we are healed. Jesus' suffering and death brought joy and life. His humiliation brought glory; his rejection brought a community of love. As followers of Jesus we can also allow our wounds to bring healing to others.
I can never get over the fact that Jesus, risen and glorified, still carries the wounds of the Cross (see Luke 24.36ff; John 20.26ff; Revelation 5.6). If there's one thing about the Gospel that assures me of its reality, and that makes it truly Good News for me, it's that fact!
