The Word of Scripture: The Word of the Spirit
The Holy Spirit does not come without the Word. But He wants to come through the harp, that is, through meditation on the word or thourgh the voices of father, mother, or others. Otherwise the devil comes. As David, Isaiah, and the entire Scripture testify, the Holy Spirit comes through the Word, according to the passage: Blessed is the man who meditates in the Law of God day and night (Psalm 1:1).
