Today, our meditation is upon the term used in the Bible, “the arm of the Lord.” The arm of the Lord and the hand of the Lord have the same meaning in Old Testament Scriptures.
Wake up, wake up, O Lord! Clothe yourself with strength! Flex your mighty right arm!
Rouse yourself as in the days of old when you slew Egypt, the dragon of the Nile. (Isa 51:9 NLT, underscoring added)
The Arm of the Lord refers to the Lords’ strength and ability to accomplish whatever He chooses to do. In other words, Jesus being referred to as “the Arm” signifies His Omnipotent and proactive nature.
Another verse that explains why one of Jesus’ names is ‘The Arm of The Lord’ is John 14:13, which declares, “If you ask anything in My name, I will do it.” Remember, when Jesus taught us how to pray in Matthew 6:6-15, He said, “pray to the Father.” Then He said, “I will do it.” Jesus is The Arm of The Lord. He is the One who gets things done. (Source: https://www.preaching.com/articles/jesus-is-the-arm-of-god)
Nevertheless, I am continually with you; you hold my right hand. (Ps 73:23 ESV)
Even there your hand shall lead me, and your right hand shall hold me. (Ps 139:10 ESV, underscoring added)
And the hand of the Lord was with them, and a great number who believed turned to the Lord. (Ac 11:21 ESV)
In the Prophets, we hear promises that the Lord would again save his people by his arm. And in Isaiah, in particular, the revealing of the arm in Isaiah 52:10 leads us in that section to see how God would save His people.
Isaiah 53 foretells of the Servant whose body would be offered as a sacrifice to pay the penalty of sin for his people. Moreover, Isaiah 59 informs us that no man was there to intercede and bring justice to the nations (v. 15). Therefore, God himself would bring salvation by his arm. Only now, in the fullness of this passage and in the fullness of time, we know that God did not send an arm. Rather, his arm is his Son.

Because Jesus is the Arm of the Lord, we need never to be afraid. Jesus promised that He would never leave us nor abandon us (Heb 13:5). That means that the might, majesty, and power of God are perpetually with each one of His children. His protection and His blessings are upon us at all times. Hallelujah, holy God!
