That's SECURITY!
Dwelling in the house of the Lord is more than a secure place!
Abiding is the word that comes to my mind.....an all encompassing word that signifies the security that comes from dwelling with Him, my Shepherd, in a deep, ongoing relationship. That's not to diminish a physical presence at a church but to always include my/your mind and heart seeking His Presence and trusting Him in all of life!
Result = True Security!
For me, that relationship is enhanced by starting each day (dwelling) with Him---and an open Bible on my lap with a cuppa securi-TEA alongside.
A security definition from the Psalms---
I have set the Lord always before me; Because He is at my right hand, I shall not be moved. (Psalm 16:8)
