“14Do not be bound together with unbelievers; for what partnership have righteousness and lawlessness, or what fellowship has light with darkness? 15Or what harmony has Christ with Belial, or what has a believer in common with an unbeliever?” 2 Cor. 6:14-15
I remember reading years ago in F Lagard Smith’s book, WHO IS MY BROTHER?, where he suggested that pretty much any relationship we have in the world is fellowship, even at a cook-out with the non-christian next door neighbor. I believe he used this approach to justify the fellowship that he was having with a denomination in England where he worshipped and lived. But biblical fellowship is much more narrowly defined as I illustrate in my graphic below. We fellowship with God and with God’s covenant people. We “associate” with the world as the Apostle Paul says in 1st Corinthians 5. Association is necessary, but it is not fellowship. And then there are a segment of people in the world, who because of their sin, with whom we have nothing to do. Christians do not fellowship with error. We do not fellowship with sin. We fellowship with God and with His people. We need to keep this straight.
