Jesus had a lot of respect for his cousin, John the Baptist, saying, “Among those born of woman, there has not arisen anyone greater than John the Baptist.” His mother probably told him about her participation in the birth.
I’ve always thought that God was gracious to Mary to guide her to visit her elderly relative, Elizabeth, and her unborn baby. The unborn John the Baptist told his mom via the Holy Spirit that Mary was pregnant with the Messiah.
That allowed the two women who were experiencing miraculous pregnancies to talk about the implications for three months. I’m sure it helped prepare Mary to go face Joseph and the rest of Nazareth as an unmarried pregnant girl.
John the Baptist lived out in nature. Perhaps that was the only way he could commune so deeply with God.
Once he started his ministry, he also started looking for someone. Which one was the Messiah? Did his mother already tell him it was his relative Jesus? Did Jesus and John have a friendship as children? On this, the Bible is silent.
There are so many things that I’d love to know, and I’m happy to believe that all my questions will eventually be answered. Just as all the questions of John the Baptist were.
