Be not deceived, evil communications corrupt good manners.(1 Cor.15:33), But let me tell you that evil associations do not only corrupt good manners but it will surely destroy glory, destiny and cut short lives. 2 Corinthians 6:14 says “be ye not unequally yoked together with unbelievers:for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness”.
One thing that can easily destroy a Christian is to sit in the counsel of evil people. Blessed is the man that walketh not in the counsel of the ungodly, nor standeth in the way of the sinners, nor sitteth in the seat of the scornful. (Psalm 1:1)
Dinah the daughter of Leah, which she had for Jacob made a terrible mistake of going to meet the daughters of the land of Succoth, there she was defiled by Shechem the Prince of Hamor.(Gen.34:1-2). Deuteronomy 7:1-6,God clearly warned the children of Israel not to make any covenants with the people of the land of Canaan, they must not marry them but instead destroy them and there gods.
Again, if Samson had not gone to Gaza of the land of the Philistines, he will not have suddenly lost his glory (Judges 16:1-31). Where and who are you sitting or communing with? 
7 Destructive Effects Of Evil Associations:

Aren’t we supposed to not just have Christian friends? Because how will we be salt and light in our culture if we only live life in solitude, or for that matter, are only fellowshipping with church members? I really would rather not have any non-Christian friends, but I feel it is my responsibility to interact with those who don’t share my faith for the purpose of hopefully influencing them for Christ.
It’s talking about partaking of evil with evil people and with Christans out of fellowship and doing evil.
