2 Corinthians 5:17

Wherefore if any man is in Christ, he is a new creature: the old things are passed away; behold, they are become new. [By his spiritual participation in the death and resurrection of Christ, Paul had become a regenerated man, and as such he refused to judge or look upon men after that carnal, superficial, unregenerate method which estimates them according to outward appearances, and not according to their inward spiritual life. In asserting this great principle he is reminded that before his conversion he had known and judged Christ after this carnal fashion. The allusion suggests that if he made a woeful mistake in thus doing, his enemies were even now following in his footsteps in thus judging him, a minister and servant of Jesus Christ. Christian men, being spiritual beings, are to be judged as such. The old standards of the law can not be applied to them; they are not to be accepted because they are children of Abraham, nor rejected because they are Gentiles. To them all things are become new, and they must judge and be judged by the new environment into which the providence of God has brought them.]
