2 Corinthians 5:11-17 (KJV)

11 Knowing therefore the terror of the Lord, we persuade men; but we are made manifest unto God; and I trust also are made manifest in your consciences.
12 For we commend not ourselves again unto you, but give you occasion to glory on our behalf, that ye may have somewhat to answer them which glory in appearance, and not in heart. 13 For whether we be beside ourselves, it is to God: or whether we be sober, it is for your cause. 14 For the love of Christ constraineth us; because we thus judge, that if one died for all, then were all dead: 15 And that he died for all, that they which live should not henceforth live unto themselves, but unto him which died for them, and rose again.
16 Wherefore henceforth know we no man after the flesh: yea, though we have known Christ after the flesh, yet now henceforth know we him no more. 17 Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.
