What does Isaiah 65 teach about finding mercy?

In Isaiah 65:1, God states, 'I am sought of them that asked not for me; I am found of them that sought me not.' This verse reveals God's initiative in salvation, as it is He who seeks out those who are not pursuing Him. This underscores the principle that God's mercy is not based on our seeking Him but is rooted in His sovereign will. The illustration of Mephibosheth, who felt unworthy to receive mercy from King David, parallels the grace extended to those who are spiritually impoverished. Such truths illumine the profound nature of God’s redemptive work through Christ, as He intentionally reaches out to the undeserving.
