Why is Christ described as a nail in a sure place?

In Isaiah 22, Eliakim is presented as a type of Christ, described as a 'nail in a sure place.' This imagery signifies that Christ is the anchor for our faith and the assurance for our salvation. Just like a nail can hold up the weight of various objects securely, Christ holds the glory of God and the entirety of our salvation. When we trust in Him, we find a firm foundation that will never give way. Furthermore, Eliakim’s eventual removal foreshadows Christ's sacrificial death, which was necessary for our sins to be forgiven, assuring us that those who are in Christ will never be lost.
