What was Jesus greatest commandment?

in saying its love its wrong. his greatest commandment was to each one teach one his way of life his way of life was to question the authorities of his day and in doing so he got in trouble but he never gave up and in so left a blueprint for us to follow but anyone who calls themself a christian must do as he did in this life and that was to wonder from village to village preaching the good news that all of us are the son's and daughter of God the Father Whats your thoughts!
