It’s very interesting to pay attention to how each of the four gospels begin. Matthew, a gospel that focuses on the kingdom, begins with the long genealogy of Christ, demonstrating that He is the bonafide heir of David the king. Luke, on the other hand also shows us the genealogy but not that of a king, rather it’s a genealogy of a proper and upright man. The gospel of John begins in a much different way – “In the beginning was the word, and the word was with God, and the word was God.” John is the gospel that reveals Christ’s divinity.
But what about the gospel of Mark? Mark has no genealogy what so ever. Because Mark is the gospel revealing not just the humanity of Jesus, but that in His humanity Jesus Christ took the position of a slave. And He came to us a Slave-Savior.
