Mercy and grace are two complementary aspects of God’s character that are often misunderstood. Mercy is God withholding the punishment we deserve for our sins, as seen in the Old Testament with David and the Israelites, and fulfilled in the New Testament through Christ’s sacrifice (Exodus 34:6–7; Psalm 103:8; Ephesians 2:4–5). Grace is God giving us blessings, favor, and salvation that we do not deserve (Genesis 6:8; Deuteronomy 7:7–8; Ephesians 2:8–9). Jesus embodies both mercy and grace perfectly, offering mercy by forgiving our sins and grace by granting eternal life and ongoing help in our spiritual journey (John 3:16; Hebrews 4:16). Our response to this kindness is to accept God’s mercy and grace and live in gratitude and obedience to Him, experiencing the fullness of life He provides (John 10:10).
Perfect mercy and perfect grace are found in Jesus Christ. Through His sacrifice on the cross, He has provided a way of escape, or mercy, from the consequences of sin (John 3:16; Romans 5:8). God has extended grace by providing salvation and proclaiming salvation to us through the Son, His teaching in Scripture, and through the Spirit of God at work among us. Hebrews 4:16 blends these two ideas in one powerful statement, teaching, "Let us then with confidence draw near to the throne of grace, that we may receive mercy and find grace to help in time of need."
Our only rightful response is to accept both God's mercy and His grace and accept the eternal life He offers through Jesus Christ. Through this salvation, we receive the mercy of forgiven sin and the grace of life in Christ, including eternity with Him. Jesus has come to give us life, and life abundantly (John 10:10).
