Because matters of spirituality and their understanding are not found in higher educational qualification. This is why Saul, a lawyer who later became Paul, initially had it all wrong. We receive spiritual understanding through revelation. Just as Paul encountered Jesus through revelation on his way to Damascus with a legal document in hand. He received spiritual knowledge and threw the document away.
It is important to know that whiles education teaches us to take our grievances to court, revelation teaches, forgiveness and prayer forest those who offend or grieve you. May God be our help.
