In an engine-room it is impossible to look into the great boiler & see how much water it contains.
But running up beside it is a tiny glass tube, which 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; when the tube is empty, the boiler is empty.
Do you ask, "How do I know I love God? I believe I love Him, but I want to know." Look at the gauge.
Your love for your brother is the measure of your love for God.
