God talks more than anyone you will ever meet. He talks as often as you need help. I cannot explain to you my mother’s voice. You would have to spend time with my mother.
I cannot explain to you my Heavenly Father’s voice. You will have to spend time with Him to know His voice. Obedience is impossible unless you discern His voice.
“My sheep hear my voice, and I know them, and they follow me:”
(John 10:27)
