My neighbors dog, Hunter, is crying. He's not whining because he's hurt or hungry. He isn't too cold, or too hot because it is a beautiful spring day. He has everything he needs, a big yard, fresh water, and a nice dog house. He is a young dog, about a year old, and his family is trying to teach him to stay by himself for short times. He's crying because he thinks he's alone. They are coming back, but he can't see them and he feels abandoned. So, he is lonely, even though we are right on the other side of the fence.
Isn't Hunter just like us? We don't see God and so we think that we are alone, but He is here right next to us. He is all around us. God hears our cry. He wants us to be still, to trust Him and to be at peace.
