What Is a Sign Seeker?

In chapter 11 of the Gospel of Luke, Jesus gives a retelling of the Lord's Prayer. In verse 5 he tells a parable and he frontloads it in the Joseph of the Translation with Heavenly Father giving us what we ask for when we're asking the right thing with faith. He uses this parable, drawing upon the tradition among the Jews of hospitality. And then he finishes it with the most oft-repeated commandment in Scripture, I say, into you, ask and it shall be given unto you.
