First off, you don't have to go on a shepherding call if you don't want to.
If you don't feel "qualified" you can just tell the Elder that it is not
possible for you to go.
However, if you cannot do that, and you have to go, then why not try to use the time to
express how you feel too. I am sure that the ones you will be talking to will be encouraged
to hear that you have the same feelings. Encouragement comes from being understood and having
feelings accepted rather than just firing off a barrage of scriptures or WT articles to say " this is what you should be doing"
After all it is called a shepherding call.
The Elder might not like what you say but then you will
probably never be asked to go an another shepherding call ever. Don't forget that when an MS is invited on
a shepherding call it is for "training" to be an Elder. When a MS servant is considerd for an Elder the CO nedds
to know if that brother had been on shepherding calls and how they dealt with them. If you have no desire to be an Elder
then here is the chance to nip that possibilty in the bud, as well as showing to some extent how you feel about the
congregation.
