Ephesians 1:20 (KJV) states, "Which he wrought in Christ, when he raised him from the dead, and set him at his own right hand in the heavenly places." This verse is a powerful declaration of the resurrection and exaltation of Jesus Christ. It highlights the incredible power of God and the authority that He has given to His Son.

The context of this verse is important in understanding its significance. In the preceding verses, the apostle Paul is writing to the Ephesians, expressing his gratitude for their faith in Christ and their love for the saints. He then offers a prayer for the believers, asking that they would come to know the hope of God's calling, the riches of His inheritance, and the exceeding greatness of His power toward those who believe. It is in this context that Paul speaks of the work that God "wrought in Christ."

The theme of resurrection is central to this verse. It signifies the triumph of Christ over sin and death. The resurrection of Jesus is the foundation of the Christian faith, as it validates His claims to be the Son of God and the Savior of the world. The apostle Paul emphasizes the significance of the resurrection in 1 Corinthians 15:17 (KJV), stating, "And if Christ be not raised, your faith is vain; ye are yet in your sins." The resurrection of Jesus demonstrates God's power to overcome death and fulfill His promises, giving believers hope for eternal life.

The verse also speaks of Christ being set at God's right hand in heavenly places. This imagery is rich with symbolism and theological significance. The right hand is often used in the Bible as a symbol of authority and power. By being seated at the right hand of God, Jesus is affirmed as the ruler and sovereign of the universe. This imagery is echoed in Psalm 110:1 (KJV), which states, "The Lord said unto my Lord, Sit thou at my right hand, until I make thine enemies thy footstool." This verse underscores the exaltation and reign of Christ, who has been given a name which is above every name (Philippians 2:9-10).

The exaltation of Christ also points to His role as the mediator between God and humanity. As the high priest, Jesus intercedes on behalf of believers and represents them before the Father. The book of Hebrews emphasizes the significance of Christ's position at the right hand of God, as it affirms His superiority over all creation and His ability to sympathize with human weaknesses (Hebrews 4:14-16).

In summary, Ephesians 1:20 (KJV) encapsulates the core beliefs of the Christian faith – the resurrection, exaltation, and reign of Jesus Christ. It declares the victory of Christ over sin and death, His authority as the Son of God, and His role as the mediator between God and humanity. This verse reminds believers of the hope that they have in Christ, who is seated at the right hand of God in heavenly places. It is a profound declaration of the power and authority of God, and the central place of Jesus in the divine plan of salvation.
