We are conditioned by society to believe that every voice we hear inside our mind or heart is of our own creation. This blocks us from listening to the voice of God speaking to us in our spirit.
In the book of Acts, God directed the Apostles in a dramatic way. They heard His voice inside, recognized it, and followed the direction they had been given. If we learn to hear God’s voice in our lives, we too can experience this.
For this to happen, we must be open to being used of God. This means coming against secular psychology and listening for God speaking to us in our hearts.
