@Sea Breeze, after studying with the witnesses, I am not convinced that they are the true religion and I do not know what their good news is. I thought that the good news was that they were bringing Jehovah’s word.
If you have studied as far as chapter 48 in their Bible study textbook, you should reasonably understand that the 'good news' according to JWs is that 'god's kingdom' will 'soon' end all the world's problems (by killing almost everyone, but that's a side point) by means of Jesus' bad weekend... um... I mean... ransom sacrifice.
Both the original question and the answer seem disingenuous.
It is noteworthy though that even in JW videos depicting Bible studies, they have enough self awareness to show that their 'students' are often ambivalent and unengaged with the material.
