Elder Hamilton goes on to explain how we can be like that third group.
Continually holding fast to the rod means that whenever possible we attend our Sunday meetings: sacrament meeting, Sunday School, and priesthood or Relief Society meetings. Our children and youth attend their respective meetings in Primary, Young Men, and Young Women. We should never pick or choose which meetings we attend. We simply hold fast to the word of God by worshipping and attending our Sabbath meetings.Continually holding fast to the rod means that we strive to keep all of God’s commandments, to have daily personal and family prayer, and to study the scriptures daily.Continually holding fast is part of the doctrine of Christ as taught in the Book of Mormon. We exercise faith in Jesus Christ, repent of our sins, change our hearts, and then follow Him down into the waters of baptism and receive the confirming gift of the Holy Ghost, which serves as a guide and comforter. And then, as Nephi taught, we “press forward, feasting upon the word of Christ” until the very end of our lives.
It is easy I suppose to sit in the foyer of church and catch up with friends and family, to try and have a quick presidency meeting or to gather last minute preparations for our lessons during Sunday School. I've seen this in the many wards and branches we've attended through the years. Its sad really. There is so much to learn and share in Sunday School!
Sacrament Meeting for our family has been easy in some places to attend and in others a little more difficult depending on the ages and dispositions of our children. But we've made sure that even during those difficult times, that our children know how important Sacrament Meeting is to us. Even if we're sitting in the foyer so our disruptive children don't disrupt others, they know that just because we're sitting out doesn't mean we don't whisper and sit reverently. And that training was so hard to do while they were young, but it has totally paid off!!
