Caleb is eighty-five years old, and he has waited forty-five years for a promise. Today he collects: I am still as strong today as the day Moses sent me out. Now give me this hill country.

The hill country in question is full of giants and fortified cities, which is exactly why he wants it. Jesus, meanwhile, teaches prayer that refuses to quit. Persistence is today's language. Speak it.

Caleb's secret was not his knees; it was his memory. He had carried a forty-five-year-old promise through wilderness funerals and never let it expire, and when collection day came, he asked for the hardest parcel on the map. Wholehearted following produces that kind of appetite: give me the giants' hill, because God said.

The widow and the tax collector complete the picture: prayer that will not quit, and prayer that will not pretend. Ask like her, day and night, shameless. Come like him, empty-handed and honest. And if a promise of God has been gathering dust in you for decades, do what Caleb did. Bring it back out. He remembers making it.
