Jehovah's Witnesses believe in one God, that Jesus Christ died and was resurrected, and in the authority of the New World Translation of the Bible. They do not believe in the trinity nor that hell exists, and they expect Armageddon and the end of the world to happen at any time.
Jehovah's Witnesses call God "Jehovah," believing he is the one true God. They do not accept that Jesus and the Holy Spirit are parts of God. Instead, they believe that God created Jesus and that the Holy Spirit is a force and not a person. They believe Jesus died on a punishment stake and not on a cross, they do not display crosses in Kingdom Halls, and they believe that only 144,000 people will ascend to Heaven, while all other saved humanity will live forever on a paradise on Earth.
During worship services, they do not take up collections, but they leave collection boxes near the doors. They meet on Sundays at the Kingdom Hall for a public meeting and then for a second meeting. They begin and end their meetings with a prayer. During their meetings, they discuss the Bible and supplementary Watchtower publications. Though they do not think communion wafers and wine represent the body and blood of Jesus, they take communion to honor Jehovah and recognize Jesus' death.
Jehovah's Witnesses believe they are called to spread the word of Jehovah. They go door to door and distribute brochures and leaflets, encouraging others to accept Jehovah as the one true God, live a moral life, obey God's commandments and serve as a witness to others. They do not celebrate birthdays because they think such celebrations displease God. They do not celebrate Easter or Christmas, thinking both are pagan and not based on the Bible.
