Despite the joy the people felt from the Savior's visit, despite their love for Him and their enthusiasm to learn from Him, they still didn't fully understand His teachings. We have all been there when we don't quite totally understand a doctrine, a scripture, something spoken by one of the brethren, or a policy. The Savior doesn't condemn the people for their lack of understanding. Instead, He invites them to come to know and understand for themselves, and gives them some steps they can take to get there.
