We have driven (and other people have driven) our children to the Temple on many occasions to do baptisms for the dead. But David went through for his own endowments. He came out a a garment wearing priesthood man of God!
Wearing the Temple Garment
Once people are endowed, they have the blessing of wearing the temple garment throughout their lives. They are obligated to wear it according to the instructions given in the endowment. Those who have been endowed in the temple must remember that the blessings that are related to this sacred privilege depend on their worthiness and their faithfulness in keeping temple covenants.
The garment provides a constant reminder of the covenants made in the temple. The garment should be treated with respect at all times. It should not be exposed to the view of those who do not understand its significance, and it should not be adjusted to accommodate different styles of clothing. When worn properly, the garment provides protection against temptation and evil. Wearing the garment is an outward expression of an inward commitment to follow the Savior. ~From LDS.org
As I waited for him in the celestial room I imagined waiting for my children in the Celestial Kingdom. While it's a beautiful place, and a place I can't wait to be in, it was made so much better with family! David had so many insights, he picked up on way more than I did in my first year! He is a product of a family that has always put the Gospel of Jesus Christ in top priority He is also a product of regular personal scripture study and prayer, mission preparation and service to others- and those are things he has done for himself. He has two brothers and four sisters that will be following his footsteps shortly. I look forward to seeing each of my children in that special temple room! It makes all those silly things like dishes, laundry, curfews, homework, jobs, and cleaning their rooms worth it.
