from places locked in memory,
or perhaps by soaring , thrilling music heard,
or some glory seen about us -
"all these yearnings, longings are Homesickness,
a wanting in full what is only hinted at.
These are the things that conjure in our emotions the Things Unseen."
All these longings are what enable us to keep our eyes fixed on our true destination, our Heavenly one.
In the meantime, these are used by our Lord to make us run away from all our troubles outside and 'go home' to Him, our dwelling place in the Here and Now.
He that hath made his refuge God
shall find a safe secure abode,
Shall walk all day beneath His shade
And there at night shall rest his head.
