The “lot” (“lots” – plural) was an ancient method to determine choices. It was not a game but a method to determine God’s will and all those involved were apparently willing to accept the outcome.
But the real message of this verse is not about “the lot.” Instead it is the fact that God knows what is best and will do it in our lives. The question is whether we are comfortable to let Him handle it or not.
This verse is a reminder that we can try anything and everything we can think of to make things happen, but the LORD has the right and power to make the final call. So, the best thing we can do it quit trying to work things out and consciously let God do what He knows is best. Our choice is to decide to accept it or fight it!
This chapter ends like it began – we do what we can do, but in the end it is all up to God. Get used to it, that’s how He rolls!
