I love this talk from Elder L. Whitney Clayton of the Presidency of the Seventy. The growth of the Church never ceases to amaze me. The coolest part about it is that, as Elder Clayton mentions, the growth of the Church means the spreading of the knowledge of a Savior to every nation, kindred, tongue, and people (Mos. 3:20).
Think about that for a second-- the more lives the Gospel touches, the more people are able to come unto Christ, learn of Him and enter on the road to salvation and exaltation. This truly is His work, and I hope to be able to contribute to its growth in any way I can (even through this small and simple blog).
I encourage you to think of a way you can share the Gospel too, and perhaps help somebody come to know their Savior.
