I love this talk by Elder Cook. He talks a lot about how the Plan of Salvation is important to us.

Our Father’s Plan—Big Enough for All His Children

I know that our Heavenly Father created this plan for us, so that we can be happy. He created this Earth and our bodies for one purpose: "...to bring to pass the immortality and eternal life of man" Moses 1:39. I know its through His plan we can return to our Heavenly Father and enjoy eternal life with Him and our families.
