I ll put it as Christ puts it. What ever you want men to do to you, do it unto them, this is the law and the prophets.
The world will be a little better, not sure if to call it love tho. Because wicked people will still exist, the foolish will be many.
The only man who showed true love go killed for it. The love we express through Christ is not just from the ability of man to be kind. But from the power of God.
True Love can only be seen and given in Christ by Christ in us.
