How do we know God's grace and mercy are sufficient?

The sufficiency of God's grace and mercy is illustrated vividly in the narrative surrounding Absalom's banishment and subsequent restoration. Just as David has the authority to decree Absalom's return, God has established a means of grace through Christ's atoning work. The New Testament affirms this in Romans 5:8, where we see that 'while we were still sinners, Christ died for us.' This powerful act of love and grace reassures us of the sufficiency of God's mercy, equipping us to approach Him with confidence as those who have been reconciled through Christ’s finished work.
