Luke 1:31
And behold, you will conceive in your womb and bear a son, and you shall call His name Jesus.
Jesus’ name, like everything else about Him, was a sign. It was given Him by divine decree through an angel, before His birth. It’s a name with a noble pedigree: the same name – Y’shua – that the conqueror of the Promised Land had centuries before. Lots of other Jews shared the name and this is fitting. For God in becoming incarnate was thrusting Himself into the normal hurly-burly of human life and allowing Himself to swept along in the normal currents of day-to-day business as usual. But in entering that life, He was also changing it forever: pulling it up into His eternal Trinitarian life and making it a participant with Him in the everlasting glory of Father, Son, and Holy Spirit. That is why His name is “The Lord is our Salvation.”
