This time the emphasis is on the entire land belonging to Abram’s descendants – so numerous will they be that they cannot be counted. This from a man who has no children at all!
The land, so visible and tangible – Abram can walk it’s length and breadth – is one part of the promise – the two halves hinged together, reliant on each other. The land will be filled by Abram’s descendants there will be enough descendants to fill the land. The promise filled out – it becomes a promise made for perpetuity – forever; it is personal – God gives it to Abram himself as well as his offspring.
A promise that is personal, powerful, and apparently impossible. But it is God who gives the land. The God of the improbable and the impossible. In fact, he specialises in just such cases!
