Christian theology
The Greek word in the New Testament that is translated in English as "sin" is "hamartia", which literally means "missing the target". 1 John 3:4 states: "Everyone who sins breaks the law; in fact, sin is lawlessness". Jesus clarified the law by defining its foundation: "Jesus replied: 'Love the Lord your God with all your heart and with all your soul and with all your mind.' This is the first and greatest commandment. And the second is like it: 'Love your neighbor as yourself.' All the Law and the Prophets hang on these two commandments." ()
