He that dwelleth in the secret place of the most High shall abide under the shadow of the Almighty. Psalms 91:1 KJV
If the shadow of Peter brought healing and cure to people, how much more will healing and wholeness come to those abiding under the shadow of the Almighty.
Insomuch that they brought forth the sick into the streets, and laid them on beds and couches, that at the least the shadow of Peter passing by might overshadow some of them. Acts 5:15 KJV
The secret place is the place of constant communion with God. We enter in by prayer and abide by faith.
