Good pick-up Divergent and they are only talking about personal matters, anything else and it's fine to be completely judgemental. In that case, there's nothing wrong with pressuring him to change his decision.
What is surprising is that it only mentions studying the Bible and meditating on what we learn. No mention of Bible aids, like the ever so important Watchtower. Although real Christians know that you can only study the Bible with Watchtower's aids.
Pity that they forget to mention that as Christians are in the New Covenant they are given the gift of having the law written in their hearts but since it only applies to less than .1% of JWs (the anointed), I guess it's not important enough to mention.
