The Bible affirms God's existence and describes Him as creator, all-powerful (omnipotent), all-knowing (omniscient), all-present (omnipresent), and perfectly loving and just.

The Bible does not name Cain's wife. Based on the Genesis narrative, she must have been a descendant of Adam and Eve (a sister or niece) as they were the first and only human couple on earth at that time. Intermarriage was necessary for humanity to populate the earth.

The Old Testament recounts the story of creation, the covenant with Israel, the Law, and prophecies about the coming Messiah. The New Testament centers on the life, ministry, death, and resurrection of Jesus Christ (the fulfillment of the Old Testament), the establishment of the Church, and instructions for Christian living.
