Moses had a speech impediment. God doesnt choose what we think he should choose. His advice was sound.
When Jesus finished these sayings, the effect was that the crowds were astounded at his way of teaching
.Students are not greater than their teacher. But the student who is fully trained will become like the teacher.
The crowds were astounded by Jesus' teaching because of its quality, not because he was a buffoon. Of all of JW's, the GB should be "fully trained," and like Jesus, should they not?
Jesus was perfect and spent eons beside the perfect creator of the universe. Moses, was surrounded by imperfect people for 100 years or so. Do the math.
