The answer is: A scorpion

Luke 11:12

In the parable known as the "Good Father," Jesus uses the warm relationship between a father and his child to illustrate how God answers prayers with generosity and care. When a son asks for an egg—something wholesome and nourishing—a loving father would assuredly not give him a scorpion, which symbolizes danger and harm.

Think about it: eggs represent sustenance; they're a staple food embraced by many cultures. In contrast, snakes, scorpions, and other such creatures were often seen as harmful in ancient texts. It’s as if Jesus wants to drive home an important message: when we seek something good, it's unfathomable that we would receive something that bites back.

Additionally, this parable resonates with other profound teachings intertwined throughout Scripture. For instance, in Matthew 7:9-11, a similar analogy is used, further underscoring the sentiments of divine benevolence in providing for our needs. This kind of narrative beautifully echoes God’s promise of paternal care, depicted time and again in both the Christian and Hebrew writings.

Ever thought about the vividness of these illustrations? They pull generally relatable concepts—like parental care—making complex spiritual truths more accessible. So next time you're asking for your own “egg,” remember that you're part of a bigger picture: a relationship filled with loving considerations. Just like that supportive father, there's a universal call for recognizing the goodness in asking and the joy of nurturing love from unexpected sources!
