Matthew 13:1-17 Why Parables?

To you it has been given to know the secrets of the kingdom of heaven, but to them it has not been given. For to the one who has, more will be given, and he will have an abundance, but from the one who has not, even what he has will be taken away. I. Parables judge unbelief, vv10-13. II. Parables fulfill prophecy, vv14-15. III. Parables magnify God's grace, vv16-17.
