2 Corinthians 13:3-5

New Catholic Bible

³ This will give you the proof you seek that Christ is speaking in me. He is not weak in dealing with you, but he is powerful among you. ⁴ For he was crucified in weakness, but he is now alive by the power of God. Similarly, we are weak in him, but in dealing with you we will live in the power of God.

Examine Yourselves. ⁵ Examine yourselves to see whether you are in the faith. Test yourselves. Do you not realize that Jesus Christ is in you? If he is not, then you have failed the test.
