Children should be taught not to waste anything, and to save their money, but they must also be taught the habit of giving charity…. He should be told: “You are not giving away your money by putting it into the Bank of the Afterlife, where it is safest and brings the greatest returns.”…

In proportion to whatever he gives, in that measure he gains belief in the Afterlife.  ~ R’ Avigdor Miller zt”l
