How does God's arm represent His power in salvation?

In Isaiah 59:16, God states that His arm brought salvation. This metaphor of God's arm serves to illustrate His power and ability to save, distinct from human capabilities. Throughout Scripture, God's arm signifies His might and intervention in human affairs, particularly in delivering His people. The greatest manifestation of this power is seen in the life, death, and resurrection of Jesus Christ, showcasing that only through divine power can humanity be redeemed and brought into fellowship with God. It is a reminder that our hope rests not on our strength, but solely on God's sovereignty in salvation.
