The parable about The Sower and the Seed is about a sower who goes to sow his seed. He scattered his seed along the soil, but some fell along the path, and the crows picked them up and carried them away. Some seed fell onto shallow soil, it sprang up quickly, but the sun came out and burned them since it didn't have a lot of root. Some seeds, fell into the thorn bushes, they grew, but were choked. Although some of his seeds fell on good soil and grew well.
The seed that fell on the path is the man who hears about the lord, but does not understand it. The seed that fell into shallow soil is the man who receives it with joy, but when trouble or persecution comes because of the word, he quickly fades away. The seed that falls into the thorns is the man who hears about the word, but the worries of his life choke it making it unfruitful. And the seed is the man who hears about the word and takes it into his life.
The people that were listening to Jesus' story learned that they should believe the word of god and not be the kind of seed that gets taken away, choked or burned and try to be the seed that lands on good soil even because of all the trouble you might have.
Even I could use the story's message and take god's word into my life, so that I can be the kind of seed that falls amongst the good soil.
