My friend had the same experience with the 1914 generation teaching.
My friend believes one of God’s qualities is justice, therefore, sometime in the future, God will have to convince EVERY one that he exists and that all mankind will benefit from his guidance.
After reading many posters on this site, he knows it will take divine action to counter their well researched arguments .
My friend agrees that the organization of JW’s have lost their credibility. A God of justice would never execute 7 billion people because they chose not to follow the “organization” of Jehovah’s Witnesses.
