Central to Thomas’s and our faith in the resurrection is not so much that there is life after death in a risen body, but that Jesus is vindicated as Lord and God. ‘God raised him on the third day,’ said Peter in the house of Cornelius, ‘and allowed him to appear, not to all the people but to us who were chosen by God as witnesses, and who ate and drank with him after he rose from the dead. He commanded us to preach to the people and to testify that he is the one ordained by God as judge of the living and the dead.’ (Acts 10:40-42)
The Lordship of Jesus in his resurrection is the prime testimony to the faithfulness of the God of Israel to his covenant people, who were the first to be given the gospel. It was, ‘the God of Abraham, the God of Isaac, and the God of Jacob, the God of our ancestors [who] has glorified his servant Jesus’ (Acts 3:13). God is faithful to Israel, to whom belongs, ‘the adoption, the glory, the covenants, the giving of the law, the worship, and the promises’ (Romans 9:4); and especially to his promise to Abraham that, ‘in your descendants all the families of the earth shall be blessed’ (Galatians 3:8, Genesis 12:3).
