The answer is the New Testament which centers around a New Covenant. This “New Covenant”—we call it grace—is unconditional in that God says, "I will forgive you and I will see you as righteous even though you cannot keep My law (See Ephesians 2:8-9).” How can this be possible? Because the New Covenant comes through the sacrificial death of JESUS, the only one who ever lived that could and did keep all of the laws of God. He fulfilled the Law (Matthew 5:17), and died once for all as the final blood sacrifice--the Lamb of God (Hebrews 10:10). Jesus' fulfillment of the Law made the Old Testament obsolete, and replaced it with the new covenant of grace (Hebrews 8:13). He lived as a man but without sin, and through His sinless life, his death, and his resurrection from the dead, we can enter into this New Covenant relationship with God. We can be covered by the righteousness of Jesus and we can be seen as righteous before God even though we fail to keep God’s laws (2 Corinthians 5:21). That’s called grace!
