We must obey God s limits on our knowledge and not dabble in things too difficult for me. We cannot cut teeth on things that are too difficult . Within like a weaned child is my soul within me. God is forced to give us very simple black and white instructions because spiritually immature people cannot handle the many shades of gray of the complexities of spiritual life. For the immature the idea that truth has many sides is offensive.
Immaturity wants simple food.
Chewing is a difficult exercise. We might choke a few times before we get going. We might not like the effort it requires but it must be done. Making the transition from milk to meat requires accepting a change in diet. Meat is not easy to accept.
