Psalms 91:1 He that dwelleth in the secret place of the most High shall abide under the shadow of the Almighty.
It is often thought to be a negative thing to be "in someones shadows." The connotation being that you have become overshadowed by someone and no one can see you. While the world may think that is a negative, as a child of God we realize that it is a positive thing, as long as you are under the correct shadow.
There is safety in the shadows of the secret place of Almighty God. When the trials and tribulations of this world beam down on us with scorching heat, it is good and comforting to know that there is a God in Heaven who offers us the shade of His goodness and mercy.
