How do we know that God's mercy is beyond measure?

The immeasurable nature of God's mercy is rooted in His divine sovereignty and grace, as stated in 2 Timothy 1:9, where it is clear that our calling is not based on our works but according to His purpose and grace. God's mercy can differentiate between individuals, showing that it is He who decides to whom His grace is extended. This demonstrates that salvation is solely an act of God's will, reflecting His mercy that surpasses human understanding. Through Christ’s redemptive work, believers experience this grace as an unearned gift, underscoring the depths of divine mercy.
