These lyrics are inspired by the ancient prophet Isaiah 43:2, + Isaiah 43:19, + Isaiah 41:10, 41:18, 43:5
When a man or woman of Almighty God is fulfilling an appointment in obedience they are asked to do, the God of the scriptures promises them not an easy way but a certain grace that will shadow them along the way.
The Savior who quoted Isaiah often, says this too in Luke 10:19
