Secular historian Tom Holland has shown how the Christian revolution and its concept of sacrificial love has changed our world – so much so that we tend to take it for granted. Yet while love remains central to our lives and culture, it is often misunderstood and distorted. Jesus commands his friends to love one another as he loved them, and in John's gospel we see how it's practical and concrete: Jesus’ encounter with the Samaritan woman; his provision at the wedding at Cana; how he deals with Judas, and more ... Passages in Deuteronomy help us understand Jesus’ biblical concept of love and reject the way our modern culture distorts and practices “love."
