The Society talks out of both sides of its mouth. On the one hand, there are these kind articles in the Watchtower and books like Draw Close to Jehovah that highlight God's loving mercy and understanding, that indicate that whatever one can do happily is sufficient. On the other hand, there are the guilt-inducing articles and talks that constantly affirm that one's best is still not good enough!
"Put not your trust in nobles, nor in the son of man, to whom no salvation belongs." That means the "nobles" and men who run the Watchtower Society as well.
Anyone seeking salvation from that source is due for disappointment.
