John 10:4-5, NIV:  When he has brought out all his own, he goes on ahead of them, and his sheep follow him because they know his voice. But they will never follow a stranger; in fact, they will run away from him because they do not recognize a stranger's voice.

After thirty years of marriage, I can almost tell you what my wife will say in a given situation. Over a period of time of being with a person, thereís no question that you get to a point where you can almost tell just what he or she is thinking. Even when that person is not around, you can hear that personís voice in your mind. Our relationship with Christ can be much the same. Spend enough time with Him, and you will learn of His heart, have more understanding of what He thinks, and even get to where you can hear His words in your mind. There may be times when, due to circumstances, it is harder to hear His voice. Yet, His voice remains a familiar one to those who follow Him. As Jesus prayed, He asked the Father that we might be one with Him even as He was one with the Father. Just as the voice of the Father was familiar to Jesus, the voice of Jesus can be also to us--a very familiar voice.
