2 Corinthians 12:7-9

English Standard Version

So to keep me from becoming conceited because of the surpassing greatness of the revelations, a thorn was given me in the flesh, a messenger of Satan to harass me, to keep me from becoming conceited. Three times I pleaded with the Lord about this, that it should leave me. But he said to me, “My grace is sufficient for you, for my power is made perfect in weakness.” Therefore I will boast all the more gladly of my weaknesses, so that the power of Christ may rest upon me.

Reminds me of this, which is usually said in my local church as an invitation to Holy Communion:

"Come to this table, not because you must but because you may, not because you are strong, but because you are weak.

Come, not because any goodness of your own gives you a right to come, but because you need mercy and help.

Come, because you love the Lord a little and would like to love him more.

Come, because he loved you and gave himself for you.

Come and meet the risen Christ, for we are his Body"
