The religion of the Temple is a religion based on fear, control, rules and regulations. It is not a way to God. Jesus contrast himself with this failed religion, calling himself the door and the good shepherd. His sheep know him, hear his voice, follow him, and receive protection from the Father.
We know Jesus, hear his voice, and follow him through daily walking with him in prayer and fellowship, seeking to bear witness of his works to others, so they may be brought into the fold.
