C. S. Lewis said that "a man's spiritual health is exactly proportional to his love for God." It's true that God is concerned about our morals and our conduct; but He is mostly concerned with our hearts. Are they devoted to Him?
Love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength. The second is this: ‘Love your neighbour as yourself.’ There is no commandment greater than these.” -Mark 12: 30-31
