Do we really love God or is it just words?

"If you would know the measure of your love for God, just observe your love for your fellowman. Our compassion for others is an accurate gauge of our devotion to God." Rev. Billy Graham Let us love one another; for love is of God; and everyone who loves is born of God, and knows God.... And this commandment we have from Him, that he who loves God loves his brother also. 1 John 4:7,21
