The following is a guest post, by Cristofer Urlaub, from Philosophies of Men Mingled With Scripture. Thanks Cristofer! Enjoy!
There's a basic mathematical principle that says: If A = B and B = C, then A = C. This principle can be applied in scriptures. For example, in John 17:3, we read,
"And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent."
In other words, Eternal life = Knowing God.
Next, Mosiah 5:13 says,
"For how knoweth a man the master whom he has not served, and who is a stranger unto him, and is far from the thoughts and intents of his heart?"
In other words, Knowing God = Serving God.
Finally, Mosiah 2:17 says,
"And behold, I tell you these things that ye may learn wisdom; that ye may learn that when ye are in the service of your fellow beings ye are only in the service of your God."
In other words, Serving God = Serving Others.
So if Eternal Life = Knowing God = Serving God = Serving Others,
Then Eternal Life = Serving Others.
Eternal Life is service to those around us. This makes sense, since Heavenly Father, who has eternal life, is entirely dedicated to helping us. In Moses 1:39, Christ says,
"For behold, this is my work and my glory—to bring to pass the immortality and eternal life of man."
His entire existence is dedicated to uplifting and elevating us, His children.
So if any one would like to know what the Celestial Kingdom will be like, just go work with the missionaries. Or, even better, serve a mission. Heaven is just a service project away.
