The Trinity
Christians are monotheists, which means they believe in only one God - but here's where it gets interesting. They understand this one God as existing in three different persons: the Father, Son, and Holy Spirit. Think of it like water that can be ice, liquid, or steam - still the same substance but in different forms.
God the Father is seen as the creator of everything in the universe. He's the protective parent figure who loves and cares for his children but also sets boundaries through rules like the Ten Commandments. When Christians break these rules, God the Father acts as judge, ultimately deciding whether people go to heaven or hell after death.
God the Son refers to Jesus, who Christians believe is God in human form - a concept called the incarnation. Jesus came to Earth to show people what God was really like and to teach the best way to live. He performed miracles, taught about love and forgiveness, and most importantly, Christians believe he died on the cross to take punishment for everyone's sins.
Key Point: Jesus rising from the dead is crucial evidence for Christians that there's life after death and that he truly was God.
God the Holy Spirit arrived after Jesus ascended to heaven 40 days after his resurrection. This is God's active presence in the world today - the force that gives people courage, comfort, and guidance. You'll often see the Holy Spirit symbolised by a dove (representing peace) or fire (representing power). When Christians talk about answered prayers or modern-day miracles, they credit the Holy Spirit's work.
