You know, you may not; Pray for world peace?
You have to become world peace.
And, if it is what you believe?
You will have to remain peaceful when they crucify your son, if it is what you believe?
James 1;2-4 My brethren, count all joy when you fall into various trails, knowing that the testing of your faith produces patience. But let patience have its perfect work, that you may be perfect and complete, lacking nothing.
Is what you believe in, in you? There will be a test.
World peace? You may not pray for it?
It is what you must become, if it is truly your desire?
