2 Corinthians 6:10-14

as sorrowful yet always rejoicing, as poor yet making many rich, as having nothing and yet possessing all things.

Our mouth has spoken freely to you, you Corinthians, our heart is opened wide.

You are not restrained by us, but you are restrained in your own affections.

Now in the same way in exchange—I am speaking as to children—open wide your hearts to us, you as well.

Do not be mismatched with unbelievers; for what do righteousness and lawlessness share together, or what does light have in common with darkness?
