In a boiler room, it is impossible to look into the boiler to see how much water it contains. But running up beside it is a tiny glass tube, that serves as a gauge. As the water stands in the little tube, so it stands in the great boiler. When the tube is half full, the boiler is half full; if empty, so is the boiler. How do you know you love God? You believe you love him, but you want to know. Look at the gauge. Your love for your brother is the measure of your love for God. Keywords: Love
