I was schooled by old-time JW's. I don't even have to really fully understand your point to give a JW answer.
NO, Christendom is not just being selective with scriptures. They take them out of context and they twist them.
Watchtower enlightens us with understanding using the whole Bible. If you think a point is taken out of context or too selective, we will be glad to study with you and show you how the entire Bible is in harmony and points to God's Kingdom as the solution to man's problems.
(Hold on while I pile on.) And Christendom refuses to keep up with the chariot. Any seeming contradictions are eventually cleared up by continually examining the scriptures and praying for guidance (and reading the latest crap from WTS).
(We will show you that Watchtower somehow covers both sides of an issue over the years and refers back to whichever quote we need to prove the current understanding.)
