A lot of noise was coming from the hilltop behind Tim but all was quiet at the edge of the lake. Tim had just slipped away from the picnic to cast his favorite "top-water" when three small boys, all brothers, joined him.They stood very still and quietly watched the lure until a whistle (which Tim hardly heard) from someone in the crowd caught their attention. They moved, looked at each other and Tim, and one said, "We had better go - that was our father's whistle!" Without the slightest hesitation, off they ran toward the hilltop to their father.Tim believed there was a beautiful relationship between this father and his sons. What communication! What sensitivity! What obedience!Help us to know the sound of God's voice and to obey His message. John 10:27 "My sheep listen to My voice; I know them and they follow Me.
