Oh now Anonymity, you kinda answer your own question #3, in a second post. Kinda. Question three was: Third,
do you think He was named Jesus because it means savior? Or more specifically because he was named after Joshua who was one of the clearest foreshadowings of Christ? Deu 3:28 But charge Joshua, and encourage him, and strengthen him: for he shall go over before this people, and he shall cause them to inherit the land which thou shalt see.
DOESN'T MATTHEW 1: 21-23 say directly: "And she shall bring forth a son, and thou shalt call his name JESUS: for he shall save his people from their sins. Now all this was done, that it might be fulfilled which was spoken of the Lord by the prophet, saying, Behold, a virgin shall be with child, and shall bring forth a son, and they shall call his name Emmanuel, which being interpreted is, God with us."
There is alot to be found using, say, The Blue Letter Bible with the Strong's numbers.
But that is the heart of it: That is the first thing to say don't you think. Of course yes, I agree, as our resurrected Lord showed the two on the Road to Emmaus, the scriptures speak of Him, He is throughout His Word, redemption, the Gospel, the coming Christ, He is walked out in part, in flesh and blood history.
But the Matthew passage,the Greek and referenced Hebrew of it, nail the sticking point for the Jews at the time, and today: [The son of man, whom they crucified, whom God resurrected] Jesus is the Christ, the Son of God, as John puts it (John 20:31).
I agree very much about the importance of "His name", "life through His name". John 8:30-59 makes a clear distiction about the difference believing in Him can make without continuing into the truth of His name.
