My accounting advisor/teacher harped on more than one occasion about how good of an idea it is to put money away annually beginning when a person is in his twenties, so that by their sixties they can withdraw several hundred thousand dollars to have for their retirement years.
If you do the math, it really does sound like a good investment. Put aside $3000-5000 a year for forty years or so and the money will be worth several times more than the total investment.
However:
Luke 20:16-21
"And he spoke a similitude to them, saying: The land of a certain rich man brought forth plenty of fruits. And he thought within himself, saying: What shall I do, because I have no room where to bestow my fruits? And he said: This will I do: I will pull down my barns, and will build greater; and into them will I gather all things that are grown to me, and my goods. And I will say to my soul: Soul, thou hast much goods laid up for many years take thy rest; eat, drink, make good cheer. But God said to him: Thou fool, this night do they require thy soul of thee: and whose shall those things be which thou hast provided? So is he that layeth up treasure for himself, and is not rich towards God. And he said to his disciples: Therefore I say to you, be not solicitous for your life, what you shall eat; nor for your body, what you shall put on.
And:
Matthew 19:21-24
Jesus saith to him: If thou wilt be perfect, go sell what thou hast, and give to the poor, and thou shalt have treasure in heaven: and come follow me. And when the young man had heard this word, he went away sad: for he had great possessions. Then Jesus said to his disciples: Amen, I say to you, that a rich man shall hardly enter into the kingdom of heaven. And again I say to you: It is easier for a camel to pass through the eye of a needle, than for a rich man to enter into the kingdom of heaven.
