Second Nephi 7:4

The Lord God hath given me the tongue of the learned, that I should know how to speak a word in season unto thee, O house of Israel. When ye are weary he waketh morning by morning. He waketh mine ear to hear as the learned.

Jesus will speak and teach as one who has studied the law. He will be able to stand toe to toe with the greatest scholars of his day. He will teach the Jews the truths they need to hear to bring them to salvation, if they will accept him.

Even though we get tired as we struggle through our mortal trials, God does not get tired. He is always available, always listening, always ready to come to our aid when we call upon Him. When we ask Him, He teaches us the truths of His gospel.
