II Corinthians 6:7-14

by the word of truth, by the power of God, by the armor of righteousness on the right hand and on the left, by honor and dishonor, by evil report and good report; as deceivers, and yet true; as unknown, and yet well known; as dying, and behold we live; as chastened, and yet not killed; as sorrowful, yet always rejoicing; as poor, yet making many rich; as having nothing, and yet possessing all things. O Corinthians! We have spoken openly to you, our heart is wide open. You are not restricted by us, but you are restricted by your own affections. Now in return for the same (I speak as to children), you also be open. Do not be unequally yoked together with unbelievers. For what fellowship has righteousness with lawlessness? And what communion has light with darkness?
