I have noticed when I am stressed, worried or over committed writing becomes laborious. Words and ideas will not come. It is like looking into a black hole expecting something to appear on the horizon.
When I am at peace in my world and with my God I hear the Lord's promptings as if The God of my creation, Elohim, is pouring forth ideas like the oil running down Aaron's beard. The ideas come so rapidly I can't wait to write them down. Scriptures come with deeper understandings, children's books or ideas gush in my soul.
When I read the scripture "Be still and know that I Am God" (Psalm 46:10) I understand that being still is not just being quiet, reading the scriptures, or praying. It is being at peace in my soul.
