Peace on earth and good will to men.

The oldest and deepest wish of mankind, mentioned in every true religion (in various wordings, of course). Without peace on Earth and good will to men, mankind will always be living in, at best, a purgatory. Nothing need be added either since a healthy world (that's how I usually think of it) will take care of real needs and problems as a matter of course.

Thank you, Uncle_Fester.

Edit: Jesus' words on the matter:

John: 
13:34 A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another. 
 13:35 By this shall all men know that ye are my disciples, if ye have love one to another.

And note who Jesus sees as his disciples.
