Whenever I read about the arm of the Lord, and especially the right hand or right arm of the Lord, it always speaks to me of the strength of God. It speaks of His ability to save, to renew, and to bring salvation to His people.
The arm of the Lord speaks of His might, and especially in biblical terminology, the right arm speaks of tremendous strength. This is obviously connected to Jesus being seated at the right hand of God. He is, in a sense, the right hand of God — the arm that was extended towards humanity and released what John 3:16 declares: “whoever believes in Him should not perish but have eternal life.”
Then Isaiah 53:2 creates the picture of the tender shoot, or the root out of dry ground, which is beautiful.
And especially when we look at John 1, where Nathanael says, “Can anything good come out of Nazareth?” Gospel of John 1:46
It just shows again how ordinary, and almost — dare I say — "backwards", Jesus grew up in a way. This was definitely not the place, the circumstances, or the reality where one would expect the Messiah, the King of Kings and the Lord of Lords, to come from. Born in a manger in Bethlehem, then flees to Egypt, and is raised in Nazareth in very ordinary circumstances.
The dry ground and the tender shoot speak to me of Jesus coming from such simple, ordinary and unseemly circumstances — circumstances where no one would naturally expect the Messiah to emerge.
And yet this is the arm of the Lord. The strength of God is revealed through what appears to be weak, ordinary and insignificant. Beautifully pointing to the humility of the Suffering Servant.
