Living the Gospel is a Joyful Preparation

Dear brothers and sisters, living the gospel faithfully is not a burden. It is a joyful rehearsal—a preparation for inheriting the grand glory of the eternities. We seek to obey our Heavenly Father because our spirits will become more attuned to spiritual things. Vistas are opened that we never knew existed. Enlightenment and understanding come to us when we do the will of the Father.
