If you've had your body pierced by a piercing gun or tattoo needles, then St. Thomas is a perfect patron saint for you. Thomas' life changed completely when he saw Jesus' pierced, resurrected body.
Thomas was transfixed by Jesus' pierced hands, feet, and side. Had Jesus not been painfully pierced on His cross by the nails and sword, St. Thomas might never have believed Jesus was Lord and God (Jn 20:25). Knowing Thomas needed such painful proof, Jesus may have been thinking of Thomas as the nails were pounded into His hands and feet. The nails didn't hold Jesus to the cross as much as did His love for Thomas — and for us.
Do you compare your body piercings with the piercings of others? Stop doing that, and instead compare your piercings with those of Jesus. When you look at Jesus' piercings as did Thomas, what you'll see is that Jesus is Lord and God (Jn 20:28). Then you'll see how much Jesus loves you personally. Your own heart will be pierced as you look upon Him Who was pierced (Zec 12:10) for your sins (Is 53:5). His love for you held Him on His cross.
Jesus says: "Examine My hands," My feet, and My side, pierced for love of you (Jn 20:27). "Do not persist in your unbelief, but believe!" (Jn 20:28) With Thomas, respond: "My Lord and my God!" (Jn 20:28)
