How do we know God's mercy is for sinners?

The assurance of God’s mercy for sinners is explicitly stated in Hebrews 8:12: 'For I will be merciful to their unrighteousness, and their sins and iniquities will I remember no more.' This revelation showcases God’s character as not only just but also merciful. It reflects the heart of the Gospel, where Christ came to save the lost and show mercy to the undeserving. Understanding that we are all unrighteous and in need of mercy allows us to approach God confidently, knowing He desires to forgive and accept us—not based on our worthiness, but purely on His grace. It is His delight to show mercy to those who recognize their spiritual need.
