Remember that jws use specific scriptures to twist meanings and/or point to things they don't really mean...and unless they (and all xian religions) can convince you that you are a Sinner, and therefore "bad", they won't have any congregants.
Worship should be for giving gratitude for Life and the beautiful things of creation, if you believe in god or a creator. Worship should have nothing to do with feeling guilty all the time, not measuring-up, believing you are bad, etc.
If you believe god is love and that we are created in god's image, then think about this: what loving parent would look at his/her child every day and say You Don't Measure Up, You Are Bad, You Need to Beg Me for Forgiveness, etc.?
Pretty sure that's emotional abuse.
If we think it's wrong for parents to do it, why would god? Makes no sense. Please don't define your sense of self by someone else's odd reasoning on selected scriptures.
Here's the hardest thing you'll ever do: learn to love and value yourself. Do that remembering that you were not created to be punished but that you deserve to live a beautiful life.
