The Sower.

Luke 8:4-8
4 While a large crowd was gathering and people were coming to Jesus from town after town, he told this parable: 5 "A farmer went out to sow his seed. As he was scattering the seed, some fell along the path; it was trampled on, and the birds of the air ate it up. 6 Some fell on rock, and when it came up, the plants withered because they had no moisture. 7 Other seed fell among thorns, which grew up with it and choked the plants. 8 Still other seed fell on good soil. It came up and yielded a crop, a hundred times more than was sown."
When he said this, he called out, "He who has ears to hear, let him hear.

The sower is walking down a path between areas of plowed soil that has been torn up and ready to receive the seeds. Adjacent to the field is an area of underbrush that has dominated the area, an thus everything grows thick and dense.

To me, the seeds aren't being planted individually. It's more like he's taking handfuls of seeds out of the bucket and throwing them all around him, as the word "scattering" suggests. It isn't likely to be a small area, and he knows that the seeds that fall into the plowed soil will grow (so there is plenty of opportunity). Eventually, the successful crops should outnumber the unsuccessful crops.

The seed symbolizes the word of God (which I'll be talking more about tomorrow). I'm reminding you that the sower scatters the seeds in all directions, all the while realizing that some of the seeds will not grow. The same is true when you're spreading the word of God to your friends. You can do anything and everything (practically even bend over backwards) to tell your friends about God and maybe one of them won't have anything to do with your witness.

Just like the sower, you shouldn't give up when this happens. Keep scattering the seed here and there, forward and backward, side to side. Don't worry about going a little crazy. You don't want leave your bucket of seeds full!

Someone told me a couple weeks ago to "Seize every opportunity." That's the least that you should do in this situation. You don't want to leave anybody out from hearing the gospel.
