How do we know God's mercy is for everyone?

The account of the blind man's healing in Mark 8 uniquely illustrates God's mercy. The text reveals that this healing occurred in Bethsaida, a town denounced by Jesus for its lack of repentance (Matthew 11:21-22). Despite this context of judgment, Jesus demonstrates His mercy by choosing to heal a representative sinner, thereby showing that God's grace reaches even the most undeserving. It teaches us that God's mercy is not restricted but is exercised according to His sovereign will for those whom He chooses to bring to saving grace.
