What are the practical consequences? (chapter 15)

Paul asked why were they baptized?  Why was Paul in danger all the time?  Paul was boasting about the Corinthians.  Paul died every day.  What had he to gain in Ephesus?  Why not just enjoy life by eating, drinking, and being merry?  They had to stay away from bad company that would ruin their morals.  They were to sin no more.  They should have some knowledge about God.
