1 Corinthians 14:20
Brethren, do not be children in your thinking; yet in evil be infants, but in your thinking be mature.

• Mark 12:28-34
  …Jesus answered, “The foremost is, ‘HEAR, O ISRAEL! THE LORD OUR GOD IS ONE LORD; AND YOU SHALL LOVE THE LORD YOUR GOD WITH ALL YOUR HEART, AND WITH ALL YOUR SOUL, AND WITH ALL YOUR MIND, AND WITH ALL YOUR STRENGTH…
• 2 Timothy 2:15
  Be diligent to present yourself approved to God as a workman who does not need to be ashamed, accurately handling the word of truth.
• John 4:22-24
  “You worship what you do not know; we worship what we know, for salvation is from the Jews. But an hour is coming, and now is, when the true worshipers will worship the Father in spirit and truth; for such people the Father seeks to be His worshipers. God is spirit, and those who worship Him must worship in spirit and truth.”
• Philippians 4:8
  Finally, brethren, whatever is true, whatever is honorable, whatever is right, whatever is pure, whatever is lovely, whatever is of good repute, if there is any excellence and if anything worthy of praise, dwell on these things.
• Matthew 10:16
  “Behold, I send you out as sheep in the midst of wolves; so be shrewd as serpents and innocent as doves.”
• Isaiah 6:8-13
  Then I heard the voice of the Lord, saying, “Whom shall I send, and who will go for Us?” Then I said, “Here am I. Send me!” He said, “Go, and tell this people: ‘Keep on listening, but do not perceive; Keep on looking, but do not understand.’ “Render the hearts of this people insensitive, Their ears dull, And their eyes dim, Otherwise they might see with their eyes, Hear with their ears, Understand with their hearts, And return and be healed.” Then I said, “Lord, how long?” And He answered, “Until cities are devastated and without inhabitant, Houses are without people And the land is utterly desolate, The LORD has removed men far away, And the forsaken places are many in the midst of the land. Yet there will be a tenth portion in it, And it will again be subject to burning, Like a terebinth or an oak Whose stump remains when it is felled. The holy seed is its stump.”
• Matthew 13:10-17
  And the disciples came and said to Him, “Why do You speak to them in parables?” Jesus answered them, “To you it has been granted to know the mysteries of the kingdom of heaven, but to them it has not been granted. For whoever has, to him more shall be given, and he will have an abundance; but whoever does not have, even what he has shall be taken away from him. Therefore I speak to them in parables; because while seeing they do not see, and while hearing they do not hear, nor do they understand. In their case the prophecy of Isaiah is being fulfilled, which says, ‘YOU WILL KEEP ON HEARING, BUT WILL NOT UNDERSTAND; YOU WILL KEEP ON SEEING, BUT WILL NOT PERCEIVE; FOR THE HEART OF THIS PEOPLE HAS BECOME DULL, WITH THEIR EARS THEY SCARCELY HEAR, AND THEY HAVE CLOSED THEIR EYES, OTHERWISE THEY WOULD SEE WITH THEIR EYES, HEAR WITH THEIR EARS, AND UNDERSTAND WITH THEIR HEART AND RETURN, AND I WOULD HEAL THEM.’ But blessed are your eyes, because they see; and your ears, because they hear. For truly I say to you that many prophets and righteous men desired to see what you see, and did not see it, and to hear what you hear, and did not hear it.”
• Colossians 1:9-12
