2 Corinthians 13:2-4

I said before, and still say it before I come, as being present for the second time, though I am still away from you, to those who have done wrong before, and to all the others, that if I come again I will not have pity; Seeing that you are looking for a sign of Christ giving out his word in me; who is not feeble in relation to you, but is strong in you: For he was feeble in that he was put to death on the cross, but he is living by the power of God. And we are feeble in him, but we will be living with him through the power of God in relation to you.
