It has already been stated that religion is a private matter. It is fine to elaborate what they mean to you, but it's unwise to tell adherents to other religions that your view is right and theirs is wrong. Sure, it may be true for you, but not necessarily so for others. It's just like how you can't force other people to believe that ghosts exist when they don't believe they do.
I am of Catholic faith and I commend Master Spockanort for her elaboration that is very clear. Jesus is not the Father - he is the Son - but He possesses the same God-hood the Father does. He is the Son because He was born on earth from the powers of the Holy Spirit, who is yet another Person sharing the very same God-hood. There are also instances in the Bible in which God the Father refers to Jesus as His Son, such as after Jesus' baptism in the Jordan (Matthew 3:13) and in John 3:16:
Matthew 3:13 said:
At the same time a voice from Heaven was heard, "This is my Son, the Beloved; He is my Chosen One.
John 3:16 said:
Yes, God so loved the world that He gave His only Son that whoever believes in Him may not be lost, but may have eternal life.
So you see, there are three Persons in one God: the Father, the Son, and the Holy Spirit. Collectively, they are called the Holy Trinity.
It may be hard to understand, but as St. Augustine, a Church scholar, put it, our mind and cognition is simply too small to understand the vastness of all God's powers. It's like trying to contain the whole ocean in a wee bucket.
I could, however, probably make it simpler to understand by drawing parallels to energy. Light, sound, and electricity are three kinds of energy; they are different (light is not sound, sound is not electricity, electricity is not light, and so on), but they are also the same in that they are all energy. In very simple terms which should be taken with a grain of salt, Jesus is God in a (very) roughly similar way light is energy.
Of course, I see it this way because I believe that this is true. If anyone disagrees with me because they are of different faith, I respect them.
