One of the phrases the New Testament often uses to describe Christians is 'in Christ' or 'united to Christ'. You and I are in Christ. This means his death is our death and his life is our life. It means his cross is our model and his resurrection is our hope.
Perhaps rather surprisingly, when the New Testament writers tell us how we should live, they don't often point back to the life of Jesus. Instead they take us again and again to the cross and resurrection. Whether they're talking about marriage or conflict or community or money or opposition or leadership or temptation or work or suffering, they look to the cross and resurrection. So if you want to know how to live as a Christian, you need to understand how the cross and resurrection shape our lives. The pattern of the cross and resurrection needs to become our reflex, our habit, our instinct. We need to live the cross and resurrection.
