²³ But when your eye is unhealthy, your whole body is filled with darkness. And if the light you think you have is actually darkness, how deep that darkness is!

²² “Your eye is like a lamp that provides light for your body. When your eye is healthy, your whole body is filled with light.

¹¹ But anyone who hates a fellow believer is still living and walking in darkness. Such a person does not know the way to go, having been blinded by the darkness.

¹⁸ Stop deceiving yourselves. If you think you are wise by this world’s standards, you need to become a fool to be truly wise. ¹⁹ For the wisdom of this world is foolishness to God. As the Scriptures say,

²⁰ So where does this leave the philosophers, the scholars, and the world’s brilliant debaters? God has made the wisdom of this world look foolish.

The Jews and the Law

¹⁷ You who call yourselves Jews are relying on God’s law, and you boast about your special relationship with him. ¹⁸ You know what he wants; you know what is right because you have been taught his law. ¹⁹ You are convinced that you are a guide for the blind and a light for people who are lost in darkness. ²⁰ You think you can instruct the ignorant and teach children the ways of God. For you are certain that God’s law gives you complete knowledge and truth.

You condemn idolatry, but do you use items stolen from pagan temples?^{[a] 23} You are so proud of knowing the law, but you dishonor God by breaking it.
