How does the fall of Adam relate to Mephibosheth?

Mephibosheth’s condition mirrors the spiritual lameness of humanity resulting from Adam's transgression. Just as Mephibosheth was made lame through a fall, all humanity bears spiritual lameness due to the sin of our first father. Romans 5:12 explains that through Adam, sin entered the world, causing death to spread to all men. This illustrates the depravity and inability that characterizes every person apart from the grace of God. Mephibosheth's story reinforces the reality that just as he was powerless to restore himself, we too are unable to redeem ourselves and are utterly dependent on God’s sovereign grace.
