Adam bore the image of God and was man’s federal representative. Adam rebelled against God, however, the rebellion-sin did not destroy but only defaced the imago Dei. So now man’s nature has been corrupted by the imputation of the ethical disease of sin (Romans 5:12).
God, however, promised that from the seed of the woman a new federal representative and image bearer of God would be sent to restore the defaced imago Dei of the progeny of the First Adam. This “seed” who brings the grace-gift of Salvation-Eternal Life is the Second Adam the God-Man Jesus Christ (Romans 5:8, 17; 1 Corinthians 15:22, 45). God has demonstrated in the Second Adam his love in full (John 3:16; Romans 5:8). Easter Sunday is a celebration of God’s love in full–we celebrate because we know that if having been united to Jesus by the gift of saving faith through the work of the Holy Ghost, and that having gone down with Jesus in his death, so too we shall rise with Jesus in that decisive victory of Resurrection, when the Father proclaimed that Jesus Christ the Son of God was the Salvation-King of fellow-man (Psalm 2; Psalm 110). At the Table of Fellowship Christians gather to partake of Christ’s body and blood which are a Testament of a greater covenant, the Covenant of Grace declared in Genesis 3:15; it is the New Covenant by which God is restoring the World to goodness through His Resurrection.
