“one miracle” = Jesus has done many miracles up to this time; many of them were even done previously in Jerusalem. (John 2:23) The “one” miracle Jesus is here referring to is the healing of the infirm man by the pool of Bethesda on the Sabbath. (John 5:9) Because He had healed this man on the Sabbath and thus, in the eyes of the Jewish leaders, broken the Sabbath, they sought to kill Jesus. (John 5:18) The same work had caused some to wonder and others to want to murder.

Jesus resists the temptation to answer the accusation of the crowd. Instead, He does the Father’s will and doesn’t try to justify Himself and His actions, thus beautifully illustrating (1 Peter 2:22-23).
