Believers Possess Yahweh’s Holy Spirit: Living Water

He who believes in Me [who cleaves to {and} trusts in {and} relies on Me] as the Scripture has said, From his innermost being shall flow [continuously] springs {and} rivers of living water.  (John 7:38 Amplified Bible)

Yeshua spoke of this Holy Spirit flowing through believers.  Let’s look at the verse above in context.
37 Now on the last and most important day of the feast, Jesus stood and called out [in a loud voice], “If anyone is thirsty, let him come to Me and drink!38 He who believes in Me [who adheres to, trusts in, and relies on Me], as the Scripture has said, ‘From his innermost being will flow continually rivers of living water.’”39 But He was speaking of the [Holy] Spirit, whom those who believed in Him [as Savior] were to receive afterward. The Spirit had not yet been given, because Jesus was not yet glorified (raised to honor).  (John 7:37-39 Amplified Bible)
The Great Kingdom of  Priests Chosen By Yahweh
Even from before the birth of Yeshua God intended for His people to be a kingdom of priests set apart for a holy purpose
“you shall be to Me a kingdom of priests and a holy nation [set apart for My purpose].’ These are the words that you shall speak to the Israelites.” (Exodus 19:6)
 But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar* people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light: (1 Peter 2:9)
Royal  Priests, a Peculiar People, Possess Yahweh’s Holy Spirit
Recall Yahweh’s Holy Spirit will continuously flow through us so that we will  never thirst again.
How do we act in the light of the Holy Spirit now given to us? 
What should our attitudes be like in a world overflowing in debauchery, violence and the love of sinful living ubiquitous within our society and our world?
A Holy Nation of Priests Possesses a Certain Attitude
