Commentaries:
Paul says here the reason God reveals mysteries is so that we will obey and that we will be motivated to obey Him, providing us with incentive to do what is necessary. That is why He gives us insight into some of the mysteries of the prophecies. He does not do it because we are good people, but rather He wants us to become good people. This will play some part in motivating us to do what is needful and not be like the Laodicean, who says, "I'm already good. I'm rich and increased with goods and have need of nothing." And so the Laodicean whiles away the time, wasting it when he should be redeeming it. Remember, mysteries are revealed in order to stir a person to good works.
