I don't understand the Trinity, and I'd really like it if someone could explain it to me. I don't understand it because 1) It's a generally confusing subject IMO, and 2) Jesus said that he did not come to change the law but to fulfill it, yet the concept of three in one is a pretty drastic change from the teachings of Abraham, Moses, etc. So if someone could explain it, I'd really appreciate that.
Good question, it's not a concept I think anyone can fully understand simply because it's the finite mind trying to grasp the infinite. I'm hesitant to use an example because I don't mean to limit God in any way, but much like how you can be one person and be a parent, a child, a student, a teacher, a basketball player or whatever, the three aspects of God, Father, Son, and Holy Spirit, each have a different role to play in His plan for mankind.
The Son and the Holy Spirit are not new to the New Testament.
Isaiah 63:8-10
For He said, “Surely they are My people, children who will not lie.” So He became their Savior. In all their affliction He was afflicted, and the Angel of His Presence saved them; in His love and in His pity He redeemed them; and He bore them and carried them all the days of old. But they rebelled and grieved His Holy Spirit; so He turned Himself against them as an enemy, and He fought against them.
Isaiah 9:6
For unto us a Child is born, unto us a Son is given; and the government will be upon His shoulder. And His name will be called Wonderful, Counselor, Mighty God, Everlasting Father, Prince of Peace.
Proverbs 30:4
Who has ascended up into heaven, or descended? Who has gathered the wind in his fists? Who has bound the waters in a garment? Who has established all the ends of the earth? what is His name, and what is His Son's name, if you know?
And there are many other verses which establish the presence of the Son and the HS. Add to that the Hebrew term often used in the Old Testament referring to God, 'Elohim', is used to denote a plurality greater than two. The three distinct roles of God magnify one another. 1x1x1 rather than 1+1+1.

Starve, please elaborate if you feel compelled. Some of us may be more sympathetic to your beliefs than you may think.
