This passage most definitely seems to be about the Messiah. In Isaiah 51:9 it talks about the arm of the Lord putting on its strength. It seems to be a call for Jesus to come to action. In Isaiah 51 it seems to indicate that Jesus actually parted the Red Sea among other things (ex. “Pierced the dragon” I believe would mean him, Jesus Having some kind of victory over the enemy the devil Satan). In Isaiah 52 He’s called to be the Messiah:
13 Behold, My servant will prosper,
He will be high and lifted up and greatly exalted.
14 Just as many were astonished at you, My people,
So His appearance was marred more than any man
And His form more than the sons of men.
15 Thus He will sprinkle many nations,
Kings will shut their mouths on account of Him;
For what had not been told them they will see,
And what they had not heard they will understand.
Interesting that it states “His appearance was marred more than any man“. I always thought the movie “The Passion of the Christ” was an exaggeration in terms of the physical suffering Jesus went through, but in light of this verse, perhaps not. Jesus’ appearance was marred more than any man, so they really must have damaged Him. It was physical because it reiterates later in the same verse “And His form more than the sons of men“.
This fits with part of earlier devotions regarding healing for sin, specifically the part about “by His wounds we are healed“. Jesus not only died for us, but also suffered and somehow this seems to be the legal grounds enabling Him to heal us (inwardly from sin induced past hurts/strongholds/beachheads the devil has in us).
