If you love Christ and His Word, you will separate yourself from the world. If a husband loves his wife, he will keep his distance from all other women, and be intimate only with his wife. For I am come to set a man at variance against his father, and the daughter against her mother, and the daughter in law against her mother in law. And a man's foes shall be they of his own household. And he that taketh not his cross, and followeth after me, is not worthy of me.
Light is light, darkness is darkness.
There is a clear division. If you love the light, you must hate darkness. The Corinthian church was a very problematic church, one of the main problems was that of disunity. There were factions within the church. There was the Paul party, the Apollos party, the Cephas party, and the Christ party.
