In ancient Jewish culture, a disciple's greatest desire was to be covered in the dust of his rabbi. The disciple followed so close to his rabbi that he began to take on not only the beliefs of the rabbi, but also his personality, mannerisms, habits, thoughts, and speech. The purpose was for the disciple to be a duplicate of the rabbi so that he could then train up the next generation of disciples to mimic him. Jesus' disciples love and follow Him. It's not about doing anything for Jesus, but about doing everything with Jesus. Jesus is saying to us, "Do you love Me? Then obey Me. Do you trust Me? Then practice what I'm teaching you."
