The story of the Widow's Mite can be found in the Gospel of Mark, chapter 12, verses 41-44. Here's a version of the story for children:
One day, Jesus and his disciples were in the temple in Jerusalem, watching people as they put their money into the temple treasury. So many rich people came and gave lots of money, and everyone could hear the coins jingling as they dropped them in.
But then a poor widow put in just two small coins. They were called "mites," and they were worth very little. So the disciples saw her and were not impressed because they thought she had hardly given anything.
But Jesus called his disciples over and said, "Truly I tell you, this poor widow has put in more than all the others. They gave out of their wealth, but she, out of her poverty, put in everything—all she had to live on."
The disciples were surprised because they thought the rich people were giving the most. But Jesus explained that the widow had given all she had, while the rich people had only given a small part of their wealth. So even though the widow's offering was small, it was a big sacrifice for her.
Jesus wanted his disciples to learn that giving is not just about the amount of money you give but also about the spirit in which you provide it. The widow gave everything she had, while the rich people only gave a small part of what they had. Jesus wanted his disciples to learn that giving generously from the heart is what really matters.
So, the story of the Widow's Mite teaches us that even the smallest act of generosity can be precious and that it is not the size of the gift that matters but the heart behind it.
