"Brothers and sisters, as good as our previous experience may be, if we stop asking questions, stop thinking, stop pondering, we can thwart the revelations of the Spirit. Remember, it was the questions young Joseph asked that opened the door for the restoration of all things. We can block the growth and knowledge our Heavenly Father intends for us. How often has the Holy Spirit tried to tell us something we needed to know but couldn’t get past the massive iron gate of what we thought we already."
