How do we know that God's mercy is part of His glory?

In addressing God's glory, it becomes clear that His mercy is foundational to understanding His character. Exodus 33:19 records God's declaration that He will be gracious to whom He will be gracious, pinpointing that His mercy is a sovereign act of His will. This indicates that God's glory is displayed not only in His power but in His readiness to extend grace to those who do not deserve it. The Apostle Paul echoes this in Romans 9, affirming that it is God who shows mercy, reinforcing the concept that God's glory is intricately woven with His merciful disposition toward sinners.
