John 10:4 "When [Jesus] has brought out all his own, he goes on ahead of them, and his sheep follow him because they know his voice."
How far you walk is how far your faith is. When you know without a doubt whose voice you are following, you have no fear in your walk or your direction in life. You are able to walk with your head held high knowing who you are following. Ask yourself, are you following people or the voice of God?
