Update on knee, I fell on my knee yesterday and it made my tumor inflamed so much, so I am very worried about it. Otherwise, the pain is gone!

I have a question, and I would love anyones answer, but I really have been wondering about this. Many of you don't know, but I am not very familiar with the Bible. I just don't know all of the people, and I find that at times, I am not understanding it (My NKJV bible), so this question may bring you responses such as: does she ever read the Bible? wow, and she is Christian? and such. The reason why I am asking this here, other than a place such as Yahoo Answers, is because I know that I can trust your words, and I really appreciate your in depth, personal, responses. God, Jesus, the Lord, Holy Spirit. What are the differences of these people? When we begin a prayer, I say Dear Lord or Dear God, but when I end it I say In Jesus's name (Amen). Why do we address two different names? Are they the same people? When I pray, who is the one that is there? In Heaven when we sit on the throne next to Him, who is *He*? Sorry to burden you all with numerous questions, but it would tremendously assist me in school, life, decision making, and especially prayer, if I can have a deeper understanding of this.

Thanks to everyone who answers, you are a true blessing!

Lots of blessing and prayers your way.
