The parable of the sower is found in the triple tradition, in Matthew 13:3ff., Mark 4:3ff. and Luke 8:5ff.
In each version the word of God sown in only 25% of the territories described becomes harvestable, and in each version this wisdom is revealed only to the disciples. This is in keeping with the double-edged sword of the prophetic message of Jesus, to issue one last call to repentance before the final judgment. It is good news to the few who repent, and bad news to the many who do not.
And he said unto them, Unto you it is given to know the mystery of the kingdom of God: but unto them that are without, all these things are done in parables.
-- Mark 4:11
He answered and said unto them, Because it is given unto you to know the mysteries of the kingdom of heaven, but to them it is not given.
-- Matthew 13:11
And he said, Unto you it is given to know the mysteries of the kingdom of God: but to others in parables; that seeing they might not see, and hearing they might not understand.
-- Luke 8:10
