Do you ever hear noises that you can’t figure out? I kept hearing a grinding noise that sounded like someone was using an electric sander, so I went outside to see if I could hear where it was coming from, and didn’t hear it anymore. Then it started again, so I went outside again, I heard nothing. I decided to look out the front window and noticed that someone was in my neighbor’s driveway, so I expect that what I was hearing was a vacuum cleaner, and that the car was the cleaning lady’s. It can be the same way when hearing God’s voice. We hear it either through the scriptures, dreams or visuals, through nature, sermons, or other ways; God is not limited in how He communicates, we are the ones limited in our hearing and understanding. Just like me confirming that my neighbor had a cleaning lady at her house, God will give you confirmation that it is His voice that you are hearing, so listen carefully.
And the Lord said to Paul one night in a vision, “Do not be afraid, but go on speaking and do not be silent, Acts 18:9
