You can't tell a woman who is called by God to teach that she cannot teach the Word of God... So I think the distinction is that there's a difference between the authority of a pastor and a Bible teacher.
God's arrows of affliction are sharp and painful so He can get our attention. He won't let His beloved children get away with sin because He knows it robs us of blessings, opportunities, and even character refinement.
To have God speak to the heart is a majestic experience, an experience that people may miss if they monopolize the conversation and never pause to hear God's responses.
God has ways of shaking the world when He is at work. He literally caused the ground to quake when Jesus died on the cross.
