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.

God is the eternal, all-powerful (omnipotent), all-knowing (omniscient), all-present (omnipresent), and perfectly good Creator of all things. He exists as one God in three Persons: the Father, the Son (Jesus Christ), and the Holy Spirit (The Trinity).

According to Christian theology (based on the New Testament), Jesus is the Son of God and God in the flesh (the Incarnation). This is a central belief of Christianity, often understood through the doctrine of the Trinity.

Jesus' death on the cross is considered an atoning sacrifice. It satisfied God's justice for human sin, offering forgiveness and the way to eternal life to all who believe in Him (Romans 5:8, 2 Corinthians 5:21)

Most theologians and scholars affirm that the Bible does not contain genuine contradictions, though it does contain paradoxes and differences in perspective or audience. Apparent conflicts are often resolved through careful study of the context, language, and historical background.
