Blessings for the asking

I find it interesting that the Lord didn't discuss the offspring issue until Abraham brought it up:

2 And Abram said, Lord God, what wilt thou give me, seeing I go childless, and the steward of my house is this Eliezer of Damascus?

So many times the Lord lets us be until we ask a question or bring something up in prayer. Remember that there are many blessings He is more than willing to grant but makes conditional upon our asking for them. Well, what blessings am I missing out on? I want to be a blessing hog! What blessings could be ours in our family if only we would sincerely ask for them and seek them? I guess, as in the case with Abraham illustrated here, it starts with what righteous desires are in our hearts, righteous desires that drive us to our knees in prayer seeking them.
