God creates us for relationships. But not all relationships are good for us. Some of them are detrimental to our spiritual lives and can harm us or make us ineffective and unproductive. Ironically, the detrimental relationships that the Bible warns us about are not with regard to unbelievers or the people in the world. The apostle Paul says in 1 Cor 5:9-10, "I wrote to you in my letter not to associate with sexually immoral people— not at all meaning the people of this world who are immoral, or the greedy and swindlers, or idolaters. In that case, you would have to leave this world." The Bible warns us to watch out against certain types of believers within the church that can negatively influence us.
