“All things are permissible”?

Why does Paul say “all things are permissible, but not all things are profitable”? What does it mean to be unequally yoked? Why is that such a big deal? How exactly are we saved? Can we lose it? How do I break strongholds when it comes to addiction? Are we allowed to sell things in churches? My family life is filled with verbal abuse. What can I do?
