Matthew 13:11-13

11Jesus replied to them, “To you it has been granted to know the mysteries of the kingdom of heaven, but to them it has not been granted.

12For whoever has [spiritual wisdom because he is receptive to God’s word], to him more will be given, and he will be richly and abundantly supplied; but whoever does not have [spiritual wisdom because he has devalued God’s word], even what he has will be taken away from him.

13This is the reason I speak to the crowds in parables: because while [having the power of] seeing they do not see, and while [having the power of] hearing they do not hear, nor do they understand and grasp [spiritual things].
