JN 8:51-59
In this gospel, the Jews began to question Jesus’ authority as a prophet. They had yet to realize that he is the Messiah, son of God. They argue with Jesus questioning how he has the ability to save them from death as long as they keep his word. What Jesus meant was that there’s a promised afterlife in which they would or would not go to depending on how they lived God’s will and held their faith close.
