The trinity is a mystery, not fully understood by man and never will be (unless/until fully revealed to us in Heaven).
The Father, the Son and the Holy Spirit are all three persons within one Godhead. Very difficult for us humans to understand this. They are ONE God. They make up ONE God. I try and see it like cutting up an apple into three. Three parts of the same apple.
Even Jesus stated that he who sees Him, sees the Father. He stated also that the Father and Himself were one and the same!
Again, one could argue over this time and time again because not all things are understood by man and this is one of those cases in the bible where it most definitely is a mystery. We find it hard sometimes to believe/accept. God may not intend for us to fully understand as yet, or perhaps that comes with holiness and clarity of the holy spirit....I am unsure. Either way oneday all things will be fully revealed.
However, the parts of the bible that are understood are exactly what is necessary for me (and others) to grow spiritually and get into Heaven.
