Time passes.
Truth becomes a banana turning mushy, with gooey spots.
(Old Light).
Changing what is considered the truth is one matter but your original post asserted that Jehovah’s Witnesses use the phrase “ undeserved kindness” to show that we are generally not unworthy of Jehovahs kindness.
I asserted that JWs use the term “undeserved kindness “when they are referring to God providing a way out for mankind via Jesus sacrifice, even though he wasn’t obligated to,
It seems like you’ve gone off topic by bringing up the way they change their teachings from time to time which we all know to be so.
I think your opening post was based on a false assumption about JWs and their use of the phrase undeserved kindness and their views of our worthiness of kindness and love from him.
JWs have a lot of things wrong but let’s be fair. They don’t teach that we aren’t worthy of his love.
There is a mixed message from JWs however that indicates that even though Jehovah loves us , out of fairness to the »obedient »ones, he won’t spare us at Armageddon unless we participate in what they consider to be « worship and service ».
