"Parents, you are the ones to decide whether the minds of your children shall be filled with ennobling thoughts or with vicious sentiments. You cannot keep their active minds unoccupied, neither can you frown away evil. Only by the inculcation of right principles can you exclude wrong thoughts. Unless parents plant the seeds of truth in the hearts of their children, the enemy will sow tares. Good, sound instruction is the only preventive of the evil communications that corrupt good manners. Truth will protect the soul from the endless temptations that must be encountered. CT 121.2"
"But while men slept, his enemy came and sowed tares among the wheat, and went his way."
The EGW passage explicitly references the sowing of tares by the enemy, directly alluding to the parable in Matthew 13:25. The context of parents needing to plant good seeds to prevent the enemy from planting bad seeds further strengthens the connection.
"Let the youth be taught to give close study to the word of God. Received into the soul, it will prove a mighty barricade against temptation. “Thy word,” the psalmist declares, “have I hid in mine heart, that I might not sin against Thee.” “By the word of Thy lips I have kept me from the paths of the destroyer.” Psalm 119:11 ; 17:4 . CT 121.3"
"Thy word have I hid in mine heart, that I might not sin against thee."
Ellen White directly references Psalms 119:11 in this passage.
