Matthew 13:13-14
Therefore, I am speaking to them with parables because [although] they can see, they [really] do not perceive, and [although] they can hear, they [really] do not comprehend, and so they [utterly] fail to understand [what I am trying to get across].
Matthew 13:35
[This was] so that what was spoken by the prophet would be fulfilled, when he said [Psa. 78:2], "I will open my mouth [to speak] with parables. I will say things that have been hidden from the beginning of time."
Mark 4:33-34
And He spoke "the word" to them [i.e., the crowds] with as many such parables as they were able to receive.
1 Corinthians 13:12
For now [i.e., during the church's infant state] we see in a mirror [Note: God's word is elsewhere likened to a mirror. See James 1:22-25] indistinctly [i.e., because of having only partial knowledge and prophecy], but then [i.e., when the church matures and has the completed Scriptures], we will see face to face [i.e., clearly]. Now I have [only] partial knowledge, but then I will have full knowledge, just as [God has] full knowledge of me.
