The Covenant of Grace

Christ fulfilled the Covenant of Grace through His life, death, and resurrection, thereby accomplishing the redemption and salvation of His people. His work can be understood in the following aspects:

1. Incarnation: By taking on human nature and being born of the Virgin Mary, Christ united Himself with humanity, making it possible for Him to represent and redeem His people (John 1:14; Galatians 4:4-5).
    
2. Perfect Obedience: Christ lived a sinless life in perfect obedience to God's law, fulfilling the righteousness required by God on behalf of His people (Matthew 5:17; Romans 5:18-19; Hebrews 4:15).
    
3. Atoning Sacrifice: Christ's death on the cross served as a substitutionary atonement, satisfying the wrath of God against sin and providing forgiveness and reconciliation for those who believe in Him (Isaiah 53:4-6; Romans 3:25; 1 Peter 2:24; 1 John 2:2).
    
4. Resurrection: Christ's resurrection from the dead confirmed His victory over sin, death, and the powers of evil, demonstrating His divine power and the efficacy of His redemptive work (Romans 1:4; 1 Corinthians 15:20-22; Colossians 2:15).
    
5. Ascension and Intercession: After His resurrection, Christ ascended to the right hand of the Father, where He now serves as our High Priest and Advocate, interceding on our behalf and ensuring that the benefits of His redemptive work are applied to His people (Hebrews 7:25; Romans 8:34; Ephesians 1:20-23).
    
6. Final Consummation: Christ will return in glory to judge the living and the dead, bringing about the ultimate fulfillment of the Covenant of Grace as He ushers in the new heavens and new earth, where righteousness dwells and His people enjoy eternal life in His presence (Revelation 21:1-4; 2 Peter 3:13; 1 Thessalonians 4:16-17).

Through these aspects of His work, Christ fulfilled the Covenant of Grace, securing salvation for His people and establishing the basis for their eternal relationship with God.

"God knoweth we have nothing of ourselves, therefore in the covenant of grace he requireth no more than he giveth, and giveth what he requireth, and accepteth what he giveth."
