And these are they by the wayside, where the word is sown; but when they have heard, Satan comes immediately, and takes away the word that was sown in their hearts.
All Commentaries on Mark 4:15 Go To Mark 4
Irenaeus of Lyons
AD 202
While we are sleeping, the enemy is sowing weeds. This is why the Lord commanded his disciples to be always on the outlook. Those who are not actively bringing forth fruits of righteousness are quickly covered over and lost among the brambles. Yet if they exercise diligence and receive the word of God as a graft into themselves, they may again recover the pristine nature of humanity, created after the image and likeness of God. .
