"Jesus, come now, I can't wait"

Janet Mefferd from time to time love to say "Jesus, please come quickly" after she just announced a news that she was disgusted at.

I see that kind of response as immature. Thus, the question, can we pray Jesus to come quickly? Sure we can. In a sinful world, His children can't wait to see their Father's kingdom fully established. Nonetheless, to ask of this the way she did, instead of praying for guidance in dealing with these corruptions, is such a cop-out.
