1 Corinthians 5:9 I wrote unto you in an epistle not to company with fornicators:
10 Yet not altogether with the fornicators of this world, or with the covetous, or extortioners, or with idolaters; for then must ye needs go out of the world.
Paul again here address fellow shipping with sinners. This time it is referencing all types of sexual sins including unnatural acts in sexual relations which includes homosexuals and adultery between male and female. One thing we must note in this, it is alright to go and witness to the lost, this is just speaking of not getting caught up in their sin. In Eph. 5:10 it tells us “And have no fellowship with the unfruitful works of darkness, but rather reprove them.” He goes on to tell us here that because we live in this world where this sin continues to abound we are not to be a part of it. We are a holy people set aside for the purposes of God but we are not own holy in our own right, but are righteousness because Jesus provided for us when He washed us in His precious blood. The purpose of us staying in this world is to win these others that are sinning out of their sin to the living God.
