"The reason so many of our ministers preach tame, lifeless discourses is that they allow a variety of things of a worldly nature to take their time and attention. Unless there is constant growth in grace, we shall be wanting in words suitable for the occasion. Commune with your own heart, and then commune with God. Unless you do this, your efforts will be fruitless, made thus by unsanctified hurry and confusion. GW 272.2"
EGW directly alludes to Psalm 4:4, using the phrase 'Commune with your own heart' and connecting it to communing with God. The context in both passages emphasizes the importance of introspection and reflection before engaging in outward actions or ministry.
