Jesus was under no illusion as to why He was drawing great crowds. Miracles of healing and casting out demons attracted much attention. There were three groups of people in the crowds. There were the curious hearers. Then, there were those who believed Him but were uncommitted in following Him. Finally, there were His disciples who had submitted to His teaching. The purpose of His parables is stated in Mark 4:11,12. Many would hear, but only those who believe in Him could understand the depth of His teaching. Those who were not committed to following Him cannot understand (Psalm 25:14). The parable of the sower is the only parable recorded by all three synoptic Gospels (Matthew, Mark, and Luke). It is always the first parable and serves as a pattern for those which follow.
