The highly esteemed theologian Karl Barth had a painting of the crucifixion on the wall of his study that was painted by the artist Matthias Grunewald. In the painting there is an image of John the Baptist. The artist portrayed John the Baptist pointing his finger to the cross of Jesus in the center of the painting. It's said that when Barth would talk with a visitor about his work, he would direct them to John the Baptist in the painting, and he would say, “I want to be that finger." Barth wanted to point people to Christ.
