Does God keep secrets, and can He keep truth hidden as long as He wants?
Yes, God is a God who can keep things secret as long as He cares to. A whole body of revealed truth, including the church age and the rapture, was not revealed beforehand. He did not even give a hint of it in Old Testament prophecies. He later revealed these mysteries to Paul for the Gentile world.
Les explains that God can keep things secret as long as He cares to, and this whole volume or body of revealed truth was one of those. He just did not reveal it, and He did not even give a hint of the church age and what is called the rapture. Les notes that Old Testament prophecy was based on the prophetic Word and the Abrahamic covenant, with God saying, "I will, I will, I will." Christ came in fulfillment of that covenant to Israel as their Messiah and King, but Israel rejected Him. So God turned to the rest of the world by putting Israel into dispersion, not using the Jew except the Apostle Paul, a Jew, a Pharisee of the Pharisees of the tribe of Benjamin. To this Jew were revealed these mysteries, these secrets, so he could take them to the Gentile world and reveal them. Les also begins the timeline back with Adam, then the call of Abraham or Abram in 2000 B.C., which brought about the nation of Israel, pulled off of the main river of humanity.
