cofty may be an example of what we are talking about here. Maybe not as happy and content but feeling very aggressive in keeping their beliefs that they are so sure they have found the truth?
People do not like to give up long held beliefs. When we all used to go to the doors, we were so sure that we had the truth. We were agressive, dismissive, and arrogantly impressed that our "good works" of going door to door set us apart from others, especially the most prominent part of the whore of Babylon - Christians who accepted the free gift of salvation like children.
Then we found out that Jesus is not our mediator, we found out that we were not justified. We found out that without being justified we cannot escape the wrath of God . In a nutshell, our beliefs were not consistent with scripture.
The..."other sheep...are...not even justified". - WT 1938 pg. 104-105
Romans 5: 1 states that we have peace with God by being justified (declared righteous) by our faith.
Romans 5: 9 states : "being now justified by his blood, we shall be saved from wrath through him."
Some people are willing to live with an inconsistent wordview, others are not. An inconsistent worldview is something I could never go back to. It is a huge red flag that something is wrong and requires more attention.
