I don't know if you know this already, but Jesus is referred to in Old Testament Scripture Prophecy as the "Prince of Peace!"
Isaiah 9:6 KJV
For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace.
Here is something frightening though. Another Old Testament Prophecy:
Daniel 8:25 KJV
And through his policy also he shall cause craft to prosper in his hand; and he shall magnify himself in his heart, and by peace shall destroy many: he shall also stand up against the Prince of princes; but he shall be broken without hand.
Here is New Testament Prophecy
1 Thessalonians 5:3 KJV
For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape.
There will be one called the Anti Christ who will stand up for peace and yet thru it destroy many. That same one who will stand for peace will stand against the Prince of Peace. That one will be destroyed, but only by the return of the Prince of Peace.
Here is an Old Testament Prophecy about the future world your poems describe:
Isaiah 11:6 KJV
The wolf also shall dwell with the lamb, and the leopard shall lie down with the kid; and the calf and the young lion and the fatling together; and a little child shall lead them.
This is talked about in the very last chapter of the Bible. Revelations 22: http://www.biblestudytools.com/kjv/revelation/22-audio.html
Legalizeliberty, I know peace is of high interest to you. I hope at least you will listen to that audio above. It is a wonderful promise of things to come. But Legalize, we can seek peace, and we should, but truly peace will only last when the Prince of Peace rules. That Prince of Peace tells us how to have peace, and you are right, it is thru love. Love people and love God. Unfortunately, it is impossible to love completely and additionally the Bible tells us in the last days the love of many will become cold. That is found in Matthew 24, but I will not inundate you with more scripture.
