When God speaks to you, be alert with all of your senses. “Speak” is a metaphor for anything God “says”.
You might see something, sometimes quickly and when it’s surprising, its too easy to ignore. So pay close attention to what comes next after you ask a question or pause to listen and “hear”.
You might hear something. Still Small Voice may speak to you silently, before words.
A memory may come. An association – an idea. It can come in any good way.
And more. Events, people, book covers, songs, billboards, birds, forests, seas, lakes and rivers. Flowers. (Can you tell I love hearing God through nature?)
To get more used to this, learn to pay attention to the many kinds of “Voices of God“.
