What is another word for mystery?
The synonym is secret. It has been kept secret, and it relates to revelations given to the Apostle Paul alone from the Ascended Christ. Christ's ascended words through Paul carry more weight for us today than what He said to the Jew under the Law.
Les explains that the other word for mystery is secret, and he stresses that it has been kept secret. He repeatedly points to Deuteronomy 29 because it summarizes the revelations given to the Apostle Paul, who claims these things were kept secret and revealed to him and him alone from the Ascended Christ. Les anticipates the objection that this takes away from what Jesus said on earth; he says no, but what Christ said from His Ascended Place in Glory carries more weight for us today than what He said to the Jew under the Law. Everything Christ says from that ascended place is through Paul. This fits the larger appeal in the context to stay in the Book, seek these things out, and not leave it only to pastors, trusting God's grace to give wisdom and common sense to those who appropriate it by faith.
