God never withholds any revelation though at times He might ask us not to look or listen. An employee, doesn't expect their boss to tell them everything that's going on in the company. They expect to hear those things that the boss feels are relevant to their jobs and tasks at hand. Jesus came as servant to His master, God. Everything that God told Him to do, He did.
Obedience is the appropriate response of a servant to their master's orders.
He is both an intermediary to God and a friend. We are at the same time servants of God and friends of Jesus. We hold two simultaneous yet different relationships with God in His fullness. God is our master. He is not our employer.
