The Bible, containing Old and New Testaments, is the infallible, inspired word of God. Written by human authors under the supernatural guidance of the Holy Spirit, the Bible is the ultimate source of doctrine, instruction, correction, and reproof.
The Bible is the final authority for Christian beliefs and living and includes all that is needed for a life of godliness. It cannot be added to, subtracted from, or superseded in any way.
Any prompting from the Holy Spirit must be measured against the standard of God’s Word. God’s Word and His Spirit will never contradict.
While there are many evidences to the credibility of Scripture, such as its unified message, its majestic style, its endurance despite efforts to destroy it, and its manuscript evidence, it is the inner witness of the Holy Spirit that ultimately convinces the believer that the Bible is authoritative.
