Scripture. The sixty-six books of the Protestant canon, in their original writings, comprise the verbally inspired, inerrant Word of God.
The thirty-nine books known as the Hebrew Old Testament are God-breathed, products of the Holy Spirit’s inspiration, and thus free from error in all that they affirm (cf. Deuteronomy 18:18, 19; Psalms 19:7, 8; 119:89, 142, 151, 160; Matthew 5:17-19; John 10:35; 2 Timothy 3:16; 2 Peter 1:20-21).
For this reason, the sinner finds the way of salvation through Scripture (Romans 10:17; 2 Timothy 3:15; Hebrews 2:1-3). The believer is made fruitful (Psalm 1:2, 3) and successful in the will of God (Joshua 1:8), warned and kept from sin (Psalms 19:11; 119:9,11), made holy (John 17:17), given wisdom (Psalm 9:7) and freeing knowledge of the truth (John 8: 31, 32), taught the fear of God (Psalm 119:38), counseled (Psalm 119:24), taught, reproved, corrected, and disciplined in the way righteousness (2 Timothy 3:16) by Scripture. Scripture is, in short, the fully adequate revelation of the person, ways, and will of God.
Similarly, the twenty-seven books known as the Greek New Testament are the eternally abiding words of Jesus Christ (Matthew 24:35), and are thus the words of God (John 7:16; 12:49). The Holy Spirit enabled the writers both to recall what the Lord said (John 14:26), and to continue to receive His revelation (John 16: 12-15). As a result, the writings of the New Testament are the commandment of the Lord (1 Corinthians 14:37), are Scripture (2 Peter 3:15-16), and are God-breathed (2 Timothy 3:16).
