how do we make all humans have reference for One God?

thats not the case You have to respect people's feelings and then they do have different perception God exists within each of you so you are right to there is one god that prevails within each of us

I believe in a god... I am from the United Stated that allows all people to believe in what they choose. Who is to say which GOD is the true God? It is all in what you believe and never will there be just one God. Just like ther will never be just one color of people. Its what makes the world interesting! I would never want everyone to be the same.

We have to be tolerant and respect each other's God. I also have to be tolerant with myself: my 20-years-old God is a different one from my 50-years-old God.

that my faith get power

You cannot make someone believe the same way you do, and will always find the easiest way to start an argument over something, is to mention Religion or Spiritual beliefs. I personally believe in One God but unless that is how they believe there is nothing we can do to change a person unless they choose too.

that can not happen because everybody believes what they believe for their own individual reasons. The only way to stop our constant fighting over religion is to learn to accept other peoples beliefs and their right to believe it. Then maybe we can all be happy and live in peace
