I would choose the creation story in the Old Testament and the death and resurrection of Jesus in the New. I would start with the creation story because it displays the life God originally intended for us as humans, to live in unity with him- his beloved creation! The story displays the awesome power of God to create everything out of nothing, but also a deeply personal God that wants to do life with us. I would then choose the story of the death and resurrection of Jesus because we see the same God that created the universe coming down to be killed by the very creation he loves so much. But as Paul says, apart from the resurrection our faith and message are in vain! Jesus' resurrection proves his identity as the Son of God, and the Messiah that the Old Testament foretells. It also shows his faithfulness, as Jesus promised that he would resurrect. It also fully atones for our chosen separation from God and we can unite with him again! This God is valiantly loving!
