The Facebook pages: "We love Adventists" and someone even started a Facebook group for our book, "It's Okay NOT to be a Seventh-day Adventist." There are: Former Adventists Liturgical Group, Former Seventh-day Adventist Group, SDA Facts and Former Adventists Fellowship, for starters....

The list is much longer than this, but I just wanted to give a random sample. Very rarely do you see Former Presbyterian or Former Baptists websites or books. Why do so many former Adventists want to get the word out about the un-"biblicalness" of Adventism? One word: Love. Former Adventists want to share what they have learned with their family and friends. That's all! No conspiracy, no hatred, no wanting to get at their former church and no "keeping to the edges" of Adventism because they secretly want to be pulled back in. Nope. Simply that they want to share the gospel with those they love.
