In Ruth 2:16 we see Boaz told his workers to "let fall also some of the handfuls of purpose". He was referring to them letting some of the corn fall on purpose to provide more for Ruth - more than she'd normally glean or have to work for.
How often does God give us "handfuls of purpose"? Do we handle it as a blessing or squander it away? The next time you receive an unexpected blessing, remember God gives us things we don't deserve way more frequently than we realize. But, it's those handfuls of/on purpose that are the extras - like sprinkles on top of ice cream - that make it so much more special.
