Ok, I know what the Trinity is, but how exactly does it work? How can I explain it to someone who does not believe in the Trinity. Some people I know are confused about the trinity. They asked me, How can Jesus be his own Father? Can you please help me with this?
I don't know that anyone can effectively answer your question. I will, however, give you a few ramble thoughts to ruminatingly masticate on.
The term "God" is not a proper name. It is a "title of office". That office is held by three. In the Hebrew, plural, unlike English, is three (not two) or more.
At creation the very power that emanated from the Godhead that brought everything into creation was Jesus. As the old Negro spiritual attests, "He's got the whole world in His hands" for He, indeed, is the very "glue" that holds the whole of creation together. When the time comes He withdraws that "glue" the whole of creation will fall apart into one big lake of fire; iow, all hell will break loose.
A corporation has officers, often referred to as ("the board" of) directors. Likewise, the Godhead (the corporation) has directors.
Let's not confuse God's breath (or, spirit) of life with The Holy Spirit. God's breath of life has been passed down from Adam and all the original forms of life (animals, fish, fowl) to the present through/from their forebears. The Holy Spirit can only "possess", i.e. indwell within a believer. The operations of the two are separately distinct.
Since creation God's breath of life, which was instilled in Adam and all the various forms of life, animals, fish, fowl, etc. Since then that breath of life has been passed down from father to son to the present. In the same way that 'power' was passed down so does the power that emanates from the Father
and represents Him is the Son, Jesus Christ.

If the people you are talking with that do not believe the Trinity are of the JW variety of the Adventist persuasion the best thing you can do for your own health, well-being and sanity is not walk but run for the nearest door and
lock it! Persuing the conversation will in no wise change their minds and you will never get them out the door. With them it is simply a uselessly frustrating fruitless war of words.
