How do we know God's mercy is infinite?

In Judges 4, we observe the repeated cycle of Israel's sin and God's deliverance, which serves as a testament to His infinite mercy. The scripture reveals that even after falling into idolatry repeatedly, the Israelites cried out to the Lord, who delivered them each time. This reflects God's unchanging nature; He does not tire of our cries for mercy. His compassion and willingness to forgive are foundational to His character, encouraging believers that they cannot exhaust His grace no matter how often they stumble.
