Mark 12:41-44
And he sat down opposite the treasury, and watched the multitude putting money into the treasury. Many rich people put in large sums. And a poor widow came, and put in two copper coins, which make a penny. And he called his disciples to him, and said to them, “Truly, I say to you, this poor widow has put in more than all those who are contributing to the treasury. For they all contributed out of their abundance; but she out of her poverty has put in everything she had, her whole living.”
Any miser can give. It takes a generous heart to sacrifice.
