John came neither eating nor drinking. He behaved utterly contrary to religion and human culture, and because of this the Pharisees and scribes, the religious people, said that he had a demon.
If any regulation is made saying that we should not eat or drink, it becomes a heavy burden. On the other hand, if any rule is made saying that we must eat and drink large amounts of food and liquid, this also becomes a heavy burden.
Hallelujah, there are no regulations! Are you hungry?
All the regulations of religion are just the heavy burden of verse 28. This is why the Lord Jesus exclaimed, "Come unto me, all ye that labor and are heavy laden.." There is no need for you to labor.
( Christ versus Religion , Chapter 3, by Witness Lee)
