Superficial Christianity

In Matthew 13:4 and 19 the message of the kingdom is snatched away by birds. What happens? If we are careless with the message of the kingdom, it can be taken away. When the word of the kingdom comes, we should take time to understand it, because it is easily lost. We may even call ourselves Christian, but is it only a label, superficial, just on the surface? Is it only an outward show and not a deep Christian life? There is no substitute for the word of the kingdom as a lamp to guide our path (Psalm 119:105-112). Do we take time to understand the word of the kingdom?
