What does the Bible say about God's mercy and grace?

In Joel 2:13, the prophet commands the people to turn to the Lord with heartfelt repentance, emphasizing God's nature as gracious and merciful. This theme of divine mercy is echoed throughout Scripture, culminating in the New Testament with the sacrificial love of Jesus Christ. God's mercy is not just a passive attribute; it actively drives His redemptive work, as seen in John 3:16 where God sent His Son to provide salvation for those who believe. Additionally, passages like Ephesians 2:4-5 highlight that we were dead in our sins, but God, being rich in mercy, made us alive together with Christ. Thus, God's grace and mercy are foundational to understanding His relationship with humanity and the offer of redemption through faith.
