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
Matthew 5:1-11

The Sermon on the Mount; The Beatitudes

5 When Yeshua saw the crowds, He went up on the mountain; and when He was seated, His disciples came to Him. 2 Then He began to teach them, saying,

3 “Blessed [spiritually prosperous, happy, to be admired] are the poor in spirit [those devoid of spiritual arrogance, those who regard themselves as insignificant], for theirs is the kingdom of heaven [both now and forever].

4 “Blessed [forgiven, refreshed by Yahweh’s grace] are those who mourn [over their sins and repent], for they will be comforted [when the burden of sin is lifted].

5 “Blessed [inwardly peaceful, spiritually secure, worthy of respect] are the gentle [the kind-hearted, the sweet-spirited, the self-controlled], for they will inherit the earth.

6 “Blessed [joyful, nourished by God’s goodness] are those who hunger and thirst for righteousness [those who actively seek right standing with God], for they will be [completely] satisfied.

7 “Blessed [content, sheltered by God’s promises] are the merciful, for they will receive mercy.

8 “Blessed [anticipating God’s presence, spiritually mature] are the pure in heart [those with integrity, moral courage, and godly character], for they will see Yahweh.

9 “Blessed [spiritually calm with life-joy in Yahweh’s favor] are the makers and maintainers of peace, for they will [express His character and] be called the sons (children) of God.

10 “Blessed [comforted by inner peace and God’s love] are those who are persecuted for doing that which is morally right, for theirs is the kingdom of heaven [both now and forever].

11 “Blessed [morally courageous and spiritually alive with life-joy in God’s goodness] are you when people insult you and persecute you, and falsely say all kinds of evil things against you because of [your association with] Me. 12 Be glad and exceedingly joyful, for your reward in heaven is great [absolutely inexhaustible]; for in this same way they persecuted the prophets who were before you.

In concluding, our attitudes should reflect what our teacher Yeshua taught us in the sermon on the mount–knowing that the great kingdom of priests are a persecuted people.
