Jesus was never ashamed to tell people about the mystery of god which was kept secret.
Ro:16:25: Now to him that is of power to stablish you according to my gospel, and the preaching of Jesus Christ, according to the revelation of the mystery, which was kept secret since the world began,
But Jesus divulged this mystery and secret to whoever wanted to know it. He stated in the lead up to the parables ;
M'r:4:11: And he said unto them, Unto you it is given to know the mystery of the kingdom of God: but unto them that are without, all these things are done in parables:
Nevertheless he went about healing the sick but every time Jesus healed some person of an ailment or raised them from the Dead he divulged this secret and entrusted them to it with the order “Tell no one!”
M't:8:3: And Jesus put forth his hand, and touched him, saying, I will; be thou clean. And immediately his leprosy was cleansed.
M't:8:4: And Jesus saith unto him, See thou tell no man; but go thy way, shew thyself to the priest, and offer the gift that Moses commanded, for a testimony unto them.
M'r:7:36: And he charged them that they should tell no man: but the more he charged them, so much the more a great deal they published it;
Lu:5:14: And he charged him to tell no man: but go, and shew thyself to the priest, and offer for thy cleansing, according as Moses commanded, for a testimony unto them.
So we see that Jesus did inform the people of the secret mystery of God and immediately gives the instruction to “tell no man” otherwise it wouldn’t be a secret.
M't:13:35: That it might be fulfilled which was spoken by the prophet, saying, I will open my mouth in parables; I will utter things which have been kept secret from the foundation of the world.
