God spoke through the writers of each book of the Bible.

“The Advocate, the Holy Spirit, whom the Father will send in my name, will teach you all things and will remind you of everything I have said to you.”

“All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the servant of God may be thoroughly equipped for every good work.”
2 Timothy 3:16-17

“Above all, you must understand that no prophecy of Scripture came about by the prophet’s own interpretation. For prophecy never had its origin in the will of man, but men spoke from God as they were carried along by the Holy Spirit.”
2 Peter 1:20-21

The Bible’s message is centered on the forgiveness of sins through Jesus.

Luke 24:45-47

“All the prophets testify about [Jesus] that everyone who believes in him receives forgiveness of sins through his name.”
