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

In 1 John 3:5, we learn that 'He was manifested to take away our sins, and in Him is no sin.' This illustrates the profound truth that while we are sinners, in Christ, we are completely forgiven and no longer seen as sinful by God. John's astonishment at this grace is echoed throughout Scripture, emphasizing that our identity as children of God is rooted in Christ's righteousness, not our own merit. This grace is sovereign and freely bestowed, highlighting the mercy of God which is foundational to the Gospel.
