Because God's nature is triune, or the unity of Three, we see they mystery of three throughout the Bible. In the holy scriptures, we see the mystery of the trinity, the mystery of the tabernacle, which is tripartite, the mystery of the three peoples in the Kingdom of Heaven, and we see three levels of cleansing or of sanctification, three desert experiences, three heavens, three major feasts in Israel, tripartite man, made in the image of God, and many other examples of three throughout the Bible.
