Commentary on the Bible by Adam Clarke:  2 Corinthians 6:14

"For what fellowship, etc. - As righteousness cannot have communion with unrighteousness, and light cannot dwell with darkness; so Christ can have no concord with Belial, nor can he that believeth have any with an infidel. All these points were self-evident; how then could they keep up the profession of Christianity, or pretend to be under its influence, while they associated with the unrighteous, had communion with darkness, concord with Belial, and partook with infidels?"

But did not Jesus keep company with sinners?  How are we to bring the light of the Lord Jesus Christ to others unless we be among them?

   "O Star (the fairest one in sight),
   We grant your loftiness the right
   To some obscurity of cloud
   It will not do to say of night,
   Since dark is what brings out your light."
   (excerpt from Robert Frost's poem, "Choose Something Like a Star", 1916)

"Oh Lord, lead us not into temptation, but deliver us from evil...."

How can we not associate with sinners and not be tempted by fairer-looking ways?  And if we are tempted, what are we to do with such temptation?
