Love's quality is measured by what it will do, what it will give, what it will suffer. God so loved the world that he gave--gave his only-begotten Son, gave all, withheld nothing. That is the measure of the divine love for us: it loves to the uttermost. If you are Christ's, every energy of your mind, every affection of your heart, every power of your soul, every fibre of your body, every particle of your influence, every penny of your money, is Christ's, and all of these are to be used to bless your fellow-men and to make the world better and happier. If we love, we will give, we will suffer, we will sacrifice. If we would be like God, we must live to minister, giving our life, without reserve, to service in Christ's name.
Matthew 22:35-40: Then one of them, which was a lawyer, asked him a question, tempting him, and saying, Master, which is the great commandment in the law? Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. This is the first and great commandment. And the second is like unto it, Thou shalt love thy neighbour as thyself. On these two commandments hang all the law and the prophets. (KJV)
Joshua 22:5: But take diligent heed to do the commandment and the law, which Moses the servant of the LORD charged you, to love the LORD your God, and to walk in all his ways, and to keep his commandments, and to cleave unto him, and to serve him with all your heart and with all your soul. (KJV)
