Well, I think God speaks to each of us in a way that makes it easy for us to understand. Sometimes He speaks through our feelings, urges, gut reactions, and sometimes He speaks through words. I find that many of my messages come through songs. These songs haunt my mind. I hear them over and over.
Some people get their messages from the written word.
Other people get flashes of an idea or intuitions. I believe we can't help but do what we came here to do. Many times it takes years to prepare us. And I believe we are here to do many things, and not just one. As long as you are living your life, to the best of your ability, you won't go wrong.
