We had hints of this already at Christmas with His lowly birth and the poverty of His manger crib. Here, in Jesus' baptism, we see His humility in a yet brighter light. He lowered himself to be baptized as a sinner. The Lord of all became the Servant of all. The Sinless One stood with sinners in the water of the Jordan.
Baptism is the great equalizer.
As Peter discovered at the house of the Gentile Cornelius, God plays no favorites. It matters not whether you are a tiny infant or an adult, a prostitute, publican, or a Pharisee, Jew or Gentile, religious or unreligious, educated or uneducated, wealthy or poor, a Republican or a Democrat. We delight in distinctions. We look for ways to elevate ourselves over others. We worry about our status and dignity.
