Why have there been changes over the years in the teachings of Jehovah's Witnesses?

Since the beginning, the Watchtower Society has NEVER claimed to be an inspired prophet of God:

"We have not the gift of prophecy." - Watchtower, January 1883, page 425

Nor to be infallible:

"Nor would we have our writings reverenced or regarded as infallible." - Watchtower, December 15, 1896, page 306

Even the prophets who were divinely inspired to write portions of the Bible did not understand the meaning of everything that they wrote. (Dan. 12:8, 9; 1 Pet. 1:10-12) Even the apostles of Jesus Christ realized that there was much they did not understand in their time. (Acts 1:6, 7; 1 Cor. 13:9-12)

The Bible has shown that Jehovah enables his servants to understand his purpose in a progressive manner. (Prov. 4:18; John 16:12) The Bible shows that there would be a great increase in knowledge of the truth during "the time of the end." (Dan. 12:4) Increased knowledge often requires adjustments in one's thinking. Jehovah's Witnesses are humbly willing to make such adjustments.
