The Bible is God's message to all people. It was written by human authors, under the supernatural guidance of the Holy Spirit, to reveal God's character, to show us the true nature of humanity and to teach us how to fully live life both now and for eternity. It is the supreme source of truth for Christian beliefs and living. The original documents did not contain any errors. God has provided an avalanche of evidence to support what He claims in the Bible. God also communicates through the Holy Spirit, prayer, circumstances and His church, but these will never conflict with the truth He's already communicated in the Bible.
Psalm 12:6; 119:105,160; Proverbs 30:5; 1 Timothy 4:13; 2 Timothy 3:16; 2 Peter 1:20-21
