The Bible emphasizes salvation through faith in Jesus Christ (Ephesians 2:8-9, John 3:16). It involves repenting of sin and trusting in Jesus' death and resurrection for the forgiveness of sins.

The Bible presents God as the Creator of the universe, all-powerful (omnipotent), all-knowing (omniscient), and everywhere (omnipresent). He is often described as loving, just, and holy.

Yes, the Gospels mention Jesus having brothers (James, Joseph, Simon, and Judas) and sisters (Mark 6:3, Matthew 13:55-56). Interpretations vary on whether these were biological children of Mary and Joseph, step-siblings, or cousins.

The doctrine of the Trinity teaches that there is one God who eternally exists as three distinct persons: the Father, the Son (Jesus Christ), and the Holy Spirit. They are co-equal and co-eternal.
