Matthew 13:11
And he answered them: to you it has been given to know the secrets of the kingdom of heaven, but to them it has not been given. The answer to the disciples' question: the parables communicate differently to different hearers because the capacity to receive the kingdom's secrets has been given to the disciples but not to the crowd. The given communicates the sovereign grace of the revelation: the ability to understand the parables is itself a gift, not a natural capacity.
