Your JW baptism is as "legal and binding" as your menbership in Captain Video's Rocket Rangers. Both "organizations" were formed at the whim of men for entertainment purposes only, except that Catain Video was more up-front about the entertainment value of his club. To determine the entertainment value of RELIGION you will need to meditate on the words of the Apostle Paul, who wrote that
" It seems to me that God has put us apostles in the worst possible place. We are like prisoners on their way to death. Angels and the people of this world just laugh at us." -- 1 Corinthians 4:9 (CEV)
Paul makes similar hints in other letters too, but Suday schools don't devote a lot of time to contemplating those riddles.
For years I have said that baptism is the first step in becoming an XJW. It's similar to saying that marriage is the first step toward divorce, or that only those who are born can die.
Ultimately, these things are without meaning. Appreciate the absurd universe for the cosmic funhouse it is.
