With the completion of the New Testament in AD 89, the temporary gifts, revelatory, sign, knowledge or prophecy, tongues, knowledge are no longer necessary to confirm the authenticity of verbal inspiration, apostleship, or divine knowledge. The completed Bible is the sole authority for life and the revelation of God through Jesus Christ, God's Son. All scripture is given by inspiration of God and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: that the man of God may be perfect (complete) throughly furnished unto all good works. (
II Timothy 3:16). For example, tongues ceased or stopped for 15 centuries.
