In our entire life, love the Lord. With all your thought and understanding, He should be the first one that you are thinking of. We should love Him first and above all else. He is the author of love, that's why He is the first one that should be loved.
Love the Lord God with all your passion and prayer and intelligence and energy. In everything you do, think of Him. You will love doing things once you love Him. He is the source of life. Once you dedicate your life to Him with all your heart, soul and mind, you will have a life that nothing compares in this world.
