“And at the end of eight days, when he was circumcised, he was called Jesus, the name given by the angel before he was conceived in the womb” (Luke 2:21). So tomorrow, the 8th day after Christmas, which falls on New Year’s Day, the church year commemorates the Circumcision and Name of Jesus.
With the baby’s circumcision, He took upon Himself the burden of the Law, which He fulfilled on our behalf. And with His naming, His identity and purpose are made clear. “Jesus” means “Yahweh saves.” God saves. His very name proclaims His divinity and His saving work.
