Abram is 99. Sarai is 90. But God is Almighty, El Shaddai. That changes everything. It changes Abram to Abraham. It changes Sarai to Sarah. And it changes the male body in Israel - circumcision - a gory, bloody, painful mark to something beautiful and Christward. In this passage, we hear the Word of God proclaim the mercy and power of God in something as strange as circumcision and what it means for us today as we strive to follow Jesus.
