What do Christians believe about 'Who's who in the Trinity'?

Christians believe there is one God and He is three in one. The parts of God are called Persons: the Person of the Father, the Person of the Holy Spirit and the Person of the Son whom we also call Jesus. Each of the Persons is fully God. The Father is God, the Holy Spirit is God and Jesus is God. The three are so perfectly joined that they are one. 

The Bible teaches that the three Persons of God work together but each do different things.

Christians believe that...

God the Father sits on the throne in Heaven. He is the Creator of Heaven and earth. 

God the Son, Jesus, came to live with people over 2000 years ago. He died on the cross so that everybody everywhere can be forgiven. Then on the third day God raised Him back to life. Now Jesus lives in Heaven. He is sitting at the right hand side of Father God. The Bible teaches that because Jesus lived, died and rose again everybody everywhere can say 'Yes' to God's love and forgiveness and become close friends with God. 

When Jesus went up (to Heaven) the Holy Spirit came down (to earth). The Holy Spirit came to be with people in a new way. The Bible teaches that the Holy Spirit is ‘the Helper’. Another word for helper is ‘comforter’, ‘someone who comes alongside’. The Bible also says that the Holy Spirit is a teacher and guide. Christians believe that with the powerful help of the Holy Spirit they can learn and grow to live God's way.
