I guess such popular expression means that in this life we need to coordinate with others in order to be effective. Sure, we do need privacy but no one denies that to advance anywhere in life you do need some ‘PR’ towards your companions or neighbors. Even if you read God’s commandments in the Bible pages, you will see that they all speak about a just relationship to God, your-self and your neighbor. When one of the Pharisees asked Jesus ‘which is the greatest commandment of the Law?’ Jesus answered: “You must love the Lord your God with all your heart, with all your soul, and with all your mind. This is the greatest and the first commandment. The second resembles it: You must love your neighbor as yourself. On these two commandments hang the whole Law and the Prophets also” (Mt. 22:34-40). So this means a just and loving relationship to God, yourself and your fellow man or woman. Isn’t that the very foundation of peace anywhere you go?
Jesus also says in another Bible text: “So always treat others as you would like them to treat you, that is the meaning of the Law and the Prophets” (Mt. 7:12). This expresses some other important angle of the Law and the message of the Prophets, that is as regards its import or benefit on the person implementing the Law and instructions of the Prophets. Jesus emphasizes this lesson to us: “. . . .the amount you measure out is the amount you will be given back” (Lk. 6:38).
