There are two great commandments in the Bible. Love the Lord your God with all your heart, with all your soul, and with all your strength (Deuteronomy 6:4-5), and love your neighbor as yourself (Leviticus 19:18). Jesus says that all of the law and the prophets hang on these two commands (Matthew 22:40).
Love seems like an important thing, but what is this thing called love? Is it that happy, longing feeling you get with your parents, spouse, children, etc, or is it just actions that you have for others?
