I love this talk!  This devotional was given to missionaries at the Missionary Training Center.  It highlights the growth and blessings that will come from serving a mission.  You can feel Elder Holland's love and concern for the missionaries.  I was at the MTC the week after this devotional was given and remember hearing about it from other missionaries.  We had the opportunity to watch it in the MTC and it was such a motivator for me not only in the MTC but throughout my mission.  Pay particular attention towards the end about how missionary work teaches us about the atonement.  It's a long talk but worth it.
