I'm not having much success in finding discussion of Christians making efforts to unite, or even anything much on suggestions, plans, or hopes. Can you point me to the best forum, or set one up? I think most of us, whatever our Church, have a sick feeling that virtue and morality in much of the world is sinking, despite some evangelical success, particularly in the Soviet Union, China,and Africa.
Many of us dread the great block of communists, muslims, unions, educators, and entertainers that so aggressively seeks a universal government and is willing to cultivate chaos to achieve it. It seems obvious that only a united Christianity, with other peaceful and freedom-loving people, has much chance to prevent a steady trend of government takeover and consolidation of power by the those groups.
First you ask about how to do a personal message in the signature area of your messages. You don't - private messages are turned off due to abuse by advertisers, con men, etc.
Second, you ask about uniting Christians. I personally think that the Tribulation Period is right around the corner. So, I think that things are going to get much worse - not better. I don't claim any special knowledge on this subject, just what is written in the Holy Bible. It appears that the world is already in a nose-dive into evil chaos.
I also believe that the Rapture of the Church which is the Body of Christ is soon. This is the Church not made with human hands, a living body of all saved believers of all time. There is a big difference between a "church" and "THE CHURCH". THE CHURCH is united around Jesus Christ, and this unity will be perfected for Eternity. Many churches are having big problems in being conformed to the world while THE CHURCH is being perfected through the mighty working of God. When the time comes for the Tribulation Period, no combination of powers will be able to stop or slow it, and the world will see 7 years of horrendous evil and bloodshed like never seen in human history. This is all foretold in Bible Prophecy, and I personally believe that this time is near.
