As with Cousin John [the Baptist], the coming of Jesus was a long-awaited event; however, it was not his parents who were elderly and pleading with God to give them a baby. In fact, they were a young engaged couple; sexual relations prior to the marriage ceremony were strictly forbidden. As with Elizabeth and Zechariah, Mary and Joseph devoutly worshipped God. They were common folk. Joseph worked with his hands like many local craftsmen, a carpenter; rather than filling a priestly role at the Temple like Zechariah.
In that same portion of Scripture we see why it is that God always listened to the prayers of Jesus; it wasn’t just because Jesus was His Son. He was fervent in his praying, yes, but he was also reverentially submissive.
