2 Corinthians 13:4-5

Although he was crucified in weakness, he now lives by the power of God. We, too, are weak, just as Christ was, but when we deal with you we will be alive with him and will have God’s power. Examine yourselves to see if your faith is genuine. Test yourselves. Surely you know that Jesus Christ is among you; if not, you have failed the test of genuine faith.
