The Bible truly is the word of Almighty God. While it is sad that some don't believe. None can deny the supreme teachings that come from its pages. For example, "Treat others as you wish them to treat you." Matt 7:12.
This command came from God and for that reason, no one can quote another statement that tops it. Man may build upon the statement, but they cannot produce a quote that is superior to it. Moses knew that because he told the nation of Israel, that no civilization had laws superior laws to theirs. Deut 4.8. Because no man can out think or out create what governs human behavior better the Creator.
Treating others as one wants to be treated, destroys all the bad things that humans do to each other. No one wants to be murdered, robbed, shot, beat up, slandered, become a victim of ID fraud, etc. While evil men may do such to their victims, the same evil men don?t want someone else to do the such to them. Treating others humanely is Godly, because that is how God views behavior. He attempts to install such character in us so we can learn to be like Him.
