The mysteries in the Bible are something we all need to understand. Most of the New Testament is written in Greek.
Revelation is written in Hebrew.
Interestingly, throughout these mysteries Hebrew is interspersed. Paul was a Gentile and as you study and find the answers to these mysteries keep in mind these mysteries refer to the Gentiles. Each mystery has an absolute astounding relationship to the Hebrew alphabet. The mysteries in the Bible are in Hebrew alphabetical order with each text giving the description of the letter. Remember each letter of the Hebrew alphabet has a distinct meaning and numerical value.
