What the Bible says about Satan Stealing the Word
(From Forerunner Commentary)
The seed represents the Word of God communicated in various ways: in writing, preaching, and acts of divine intervention. Understanding the gospel comes only by the power of the Holy Spirit; without this spiritual power, the hearer is susceptible to having the knowledge of God stolen by Satan, the accuser and tempter.
God's Word sometimes falls on the ears of people whose heart is calloused by sin, on whom it makes no real impression. Like seed on a hard-packed road, it is consumed before it ever has a chance to develop. Such hardened people soon lose interest in Christ's good news and continue in the ways of the world.
