Actually, this is a parable about evangelism. The sower (believers) sow the Word (the gospel of Christ).
Those by the wayside-no response
Those on rocky ground-emotional response but self-centered
Those on weeds-double-minded. Can't let go of the world or pride
The good soil are those humble, broken-hearted who have genuine repentance.
Dear politically correct, godless, liberals who are genuinely offended at the sight of the Christ child in a manger, I have GREAT news for you! The next time you see Him, he won't be in a manger! Sadly, if you can't handle His first appearance, you're REALLY not going to like His second appearance.
Stop, Drop, and Roll won't work in Hell.
