Conducting Bible studies is not about spreading Bible truths, no ... is only about conversion. And when it is not happening, Witnesses are told to move on to a more deserving souls.
That is the truth, and all the while the JW will brazenly lie to your face and tell you that their purpose is not conversion, but rather only encouraging bible study and information.
Here are their own words from their official website F.A.Q.'s in writing.
Am I Expected to Become One of Jehovah's Witnesses if I Study the Bible With Them?No, you are not obligated in any way. Millions enjoy our Bible study program without becoming Jehovah’s Witnesses. a The purpose of the program is to show you what the Bible teaches. What you decide to do with that knowledge is up to you. We recognize that faith is a personal matter.—Joshua 24:15.
