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.
If you tell God no because He won't explain the reason He wants you to do something, you are actually hindering His blessing. But when you say yes to Him, all of heaven opens to pour out His goodness and reward your obedience. What matters more than material blessings are the things He is teaching us in our spirit.
A man can preach no better than he prays.
There is only one secure foundation: a genuine, deep relationship with Jesus Christ, which will carry you through any and all turmoil. No matter what storms are raging all around, you'll stand firm if you stand on His love.
