Why keep learning in your old age?

Suppose that we could speak with an embryo in his mother's womb and that you would tell him that the embryonic life is only a short one after which follows a real, long life. What would the embryo answer?

He might say that the life in the mother's womb is the only one and that everything else is foolishness. But if the embryo could think, he might say to himself. "Here arms grow on me. I do not need them. I cannot even stretch them. Why do they grow? Perhaps they grow for a future stage of my existence, in which I will have to work with them. Legs grow, but I have to keep them bent toward my chest. Why do they grow? Maybe life in a large world follows, where I will have to walk. My eyes grow, although I am surrounded by perfect darkness and don't need them. Why do I have eyes? Maybe a world with light and colors will follow."

So, if the embryo would reflect on his own development, he would have clues about life outside of his mother's womb, without having seen it. Look how it is the same with us. As long as we are young, we have vigor, but no mind to use it properly. Later, after we have grown in knowledge and wisdom, the hearse waits to take us to the grave. Why was it necessary to grow in a knowledge and wisdom that we can use no more? Why do arms, legs, and eyes grow on an embryo? It is for what follows.  

And so it is with us here. We grow here in experience, knowledge, and wisdom for what follows. We are prepared to serve on a higher level that follows death.

It takes faith to receive such ideas. Thankfully faith is available for us today.

Jesus said to her, “I am the Resurrection and the Life. Whoever believes in (adheres to, trusts in, relies on) Me [as Savior] will live even if he dies; and everyone who lives and believes in Me [as Savior] will never die. Do you believe this?”
