How do we know that God's mercy endures?

God's mercy is a consistent theme in Scripture, particularly highlighted in Psalms 89:33-34, where He asserts that His covenant will not be broken. This enduring mercy is evidenced in the life and ministry of Jesus Christ, who paid the ultimate price for the sins of His elect. Because His mercy is rooted in His unchanging nature, we find comfort in knowing that despite our sinfulness and failings, God's loyalty to His promises is steadfast. Thus, believers can rest assured that His mercy will always prevail, calling sinners to repentance and providing salvation through Christ.
