Jesus ALSO said to His disciples, "I speak to them in parables (which also fulfills prophecy) but to you, my disciples, I explain and speak plainly." Jesus did not come to deceive born again people who have the Spirit of God as a permanent indwelling, a deposit or guarantee of salvation!
asaph said it first.
I will open my mouth with a parable; I will utter hidden things, things from of old--

Mark 16:17
And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues;
