Saraja,
Have you read the New Testament? Why not just read Mathew, Mark, Luke and John then re-read your own question.
I questioned the Father, Son and Holy Spirit many times in the past, (I question everything). How could three be one, it appears to be an oxymoron. Then a person who is quite intelligent asked, who are you to your parents? Who are you to your wife? Who are you to your sons? Who are you to others who know you? Yet I?m just a little person. If I can be a different person to different people why would it be difficult to view God as a trinity?
No, I?m not going to change your mind either. However, the more your interested in a subject the more you should read. The more questions you should ask of people who have studied the subject, the more you will learn. May I also suggest that we learn little if anything when we look at an issue with a closed mind.
Good luck, if and when you decide to search for more knowledge, search for the truth.

Stay healthy,
Andy
