Was moses God's channel? was king david God's channel? were the appostles Gods channel? forgive me but I don't see perfection as a requirement of God's channel? I only see having the blessing of holy spirit guidance which will show up in if your teachings reflect God's word the bible.
We do not gain perfection until Jesus comes but that doesn't stop us being under the authority of our leaders! Who are allowed to have confidence in their message that they have been blessed by spirit into having the right one.
I wouldn't be defending witnesses if I hadn't looked at other christian faiths and found they no longer teach God's word the bible!
Refinement isn't an excuse but something we have to accept until Jesus comes.
Our leaders are accountable to God not men.
How were they refined?
Did God make them realize that they speak authoritively about subjects they don't know anything about?
Going from having an answer to "we don't know" isn't refinement of knowledge.
Why did the WTS even feel the need to say what they said when they clearly "didn't know" all along?
What possessed them to speak on miscarried children when they have and never had a clue about their chances of resurrection to begin with?
Why should anyone listen to foolish men who claim to speak God's truth about subjects that when "refined" reveals their ignorance and presumptuousness?
Why would God punish people for not believing them when they go from acting like they know something to admitting they don't and call it "refinement"?
