“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? And what accord has Christ with Belial? Or what part has a believer with an unbeliever? And what agreement has the temple of God with idols? For you are the temple of the living God. As God has said: “I will dwell in them And walk among them. I will be their God, And they shall be My people.” Therefore “Come out from among them And be separate, says the Lord. Do not touch what is unclean, And I will receive you.” “I will be a Father to you, And you shall be My sons and daughters, Says the Lord Almighty.””
II Corinthians 6:11-18 NKJV

“And lest I should be exalted above measure by the abundance of the revelations, a thorn in the flesh was given to me, a messenger of Satan to buffet me, lest I be exalted above measure. Concerning this thing I pleaded with the Lord three times that it might depart from me. And He said to me, “My grace is sufficient for you, for My strength is made perfect in weakness.” Therefore most gladly I will rather boast in my infirmities, that the power of Christ may rest upon me. Therefore I take pleasure in infirmities, in reproaches, in needs, in persecutions, in distresses, for Christ’s sake. For when I am weak, then I am strong.”
