The Bible,
inerrant in the original writings, is the Word of God and the final authority for faith and practice.
For assuredly, I say to you, till heaven and earth pass away, one jot or one tittle will by no means pass from the law till all is fulfilled.
(Matt. 5:18, NKJV)
All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness.
(2 Tim. 3:16, NKJV)
For prophecy never came by the will of man, but holy men of God spoke as they were moved by the Holy Spirit.
(2 Pet. 1:21, NKJV)
