And the disciples came, and said unto him,
Why speakest thou unto them in
parables?
He answered and said unto them,
Because it is given unto you to know the
mysteries of the kingdom of heaven,
but to them it is not given.
Therefore speak I to them in parables:
because they seeing see not;
and hearing
they hear not,
neither do they understand.
And in them is fulfilled the prophecy of Esaias,
which saith,
By hearing ye
shall hear,
and shall not understand;
and seeing ye shall see, and shall not
perceive:
For this people's heart is waxed gross,
and their ears are dull of hearing,
and their eyes they have closed;
But blessed are your eyes,
for they see:
and your ears,
for they hear.
Matthew 13:10,11,13-16
But the natural man receiveth not the things of the Spirit of God:
for they are
foolishness unto him:
neither can he know them,
because they are spiritually
discerned.
1 Corinthians 2:14
