You may say, "I am allowed to do anything." But I reply, "Not everything is good for you." And even though "I am allowed to do anything," I must not become a slave to anything.
You say, "Food is for the stomach, and the stomach is for food." This is true, though someday God will do away with both of them. But our bodies were not made for sexual immorality. They were made for the Lord, and the Lord cares about our bodies.
Don't you realize that your bodies are actually parts of Christ? Should a man take his body, which belongs to Christ, and join it to a prostitute? Never!
And don't you know that if a man joins himself to a prostitute, he becomes one body with her? For the Scriptures say, "The two are united into one." F33
