"And, finding there was greater happiness and peace and rest for me, I sought for the blessings of the fathers, and the right whereunto I should be ordained to administer the same; having been myself a follower of righteousness, desiring also to be one who possessed great knowledge, and to be a greater follower of righteousness, and to possess greater knowledge, and to be a father of many nations, a prince of peace, and desiring to receive instructions, and to keep the commandments of God, I became a rightful heir, a High Priest, holding the right belonging to the fathers."
In this verse Abraham is starting to choose a new life, and looking at what he wants and what he values. At the core, he wants to be happier, and to have more peace and rest. :) And everything else builds on that. He knows that God can help him find happiness. Which makes me think of "men are, that they might have joy" (2 Nephi 2:25) ... God created us so that we could be happy. Created Abraham so that he could be happy. In fact, each of us could say "I am, that I might have joy."
There is greater happiness and peace and rest for all of us, through God. That doesn't mean there will never be bad times, but it does mean that the bad times and the good, and everything that we experience is designed to make us into better, happier people in the long run. Abraham's life after this point was definitely not free of trials or sorrows, but he did find everything he was looking for. So can we.
Today, let's examine our lives and figure out what we want. Happiness? Peace? Rest? More knowledge, more guidance, more goodness, more purpose? And when we figure it out, let's work with God and start to improve/recreate our lives... talking to God about how to be happier, and then following through. :)
