The Bible is God's Word to us. Human authors, under divine guidance of the Holy Spirit wrote it. It is the supreme source of truth for Christian beliefs and living. God inspired the autographs (original writings) of the Scripture and those autographs were consequently without error. We accept the Bible as the final authority or all matters of faith and practice.
"Every word of God is flawless; he is a shield to those who take refuge in him. Do not add to his words, or he will rebuke you and prove you a liar."
"The grass withers and the flowers fall, but the word of our God stands forever."
2 Timothy 3:14-17
"But as for you, continue in what you have learned and have become convinced of, because you know those from whom you learned it, and how from infancy you have known the holy Scriptures, which are able to make you wise for salvation through faith in Christ Jesus. All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the man of God may be thoroughly equipped for every good work."
2 Peter 1:19-21
"And we have the word of the prophets made more certain, and you will do well to pay attention to it, as to a light shining in a dark place, until the day dawns and the morning star rises in your hearts. 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."
