The readings for Easter day are taken from Isaiah 65:17-25; 1 Corinthians 15:19-26; and Luke 24:1-12.
Isaiah prophesies what the resurrection of Jesus is proof of and the first witness to: God creates new heavens and a new earth. The former will not be remembered. There is rejoicing forever; no more weeping or crying or short lifespans. You will live in the house you built, eat what grows in your garden, i.e., God’s elect will forever enjoy the work of their hands. Before we call, God answers. Animals live together in harmony. No one will hurt or destroy on God’s holy mountain.
Paul proclaims in 1 Corinthians that we are not fools to be pitied. The fact is and remains established by so many witnesses over 40 days’ time that Christ has and remains risen. He is just the first of all who will also be raised because of our connectedness with Him. There will be a restoration of what has been ruined by the corruption of Adam; the longer version is described in Isaiah.
Luke records how human nature trapped in the corruption and consequences of Adam is certain that Jesus remains dead: women went to the tomb to finish the burial, the apostles refuse the women’s report of what the angels said. The angels at the tomb ask one of the very best questions ever: “Why do you seek the living among the dead?” Then the angels declare the fact that Jesus has arisen, just like He said He would. God’s promises through Isaiah were fulfilled by Jesus and so all the other promises for our future and hope must also come to pass. Indeed, God has already regenerated our souls in the image of Christ. Baptism is our birth certificate and passport; we are children of God and citizens of His everlasting kingdom of grace, peace, and life.
A very blessed Easter and Eastertide to you all.
