Whenever a prophet proclaims a new commandment from the Lord, his followers must struggle with whether or not to accept it. This can be particularly difficult when the prophet is a family member. Remember, A prophet is not without honour, save in his own country, and in his own house (Matt 13:57, italics added). Followers with the greatest faith obtain a testimony for themselves – no longer leaning on the arm of another. With Lehi's family we see that Nephi obtained his testimony of the divinity of Lehi's plan through direct revelation (1 Nephi 2:16), Sam obtained his because he believed in the words of Nephi (v. 17), and Sariah obtained it after the witness of her sons return. Laman and Lemuel, however, never obtained a testimony because they never sought for one. They had no desire to believe that their father might actually be a prophet of the Lord. When we reject the counsel of the prophets, it is often when we, like Laman and Lemuel, don't want to believe that the counsel is of the Lord. We therefore lack the desire which would bend the knee and humble the spirit.
