Hunger for Righteousness (pre-requisite for revival)

Revival is something many of us in the west long for.
Seeing many, even multitudes, coming to a sincere love of Jesus, and gratitude for his saving work on the cross. A changed life and the fellowship of believers, churches filling and going against the current trend. Old and young alike eager to be present together honouring the Lord and one another, eager to be under the word and built up in faith and looking forward to his return, together. Joining in prayer and praise and sings of worship willingly and thoughtfully, considering each other genuinely and in humility. 
How wonderful it is as in psalm 133 when the brethren agree in unity.

How does revival or even a single conversion come about? 
My answer at my current understanding as a Christian and reflecting in my own life is that at some point we must experience a hunger for righteousness.
I would also describe this as a need to be right with God and before God. Not for fear of punishment or a desire for reward (as Luther clearly stated) but simply due to an overwhelming understanding of the reality and holiness of God.
Blessed are those who hunger and thirst for righteousness, they will be satisfied.
If there is no hunger, then we will seek more elaborate tastier, but not necessarily healthier meals. 
But hunger for righteousness can never be satisfied.
Never.
Except for the cross.
At the cross all the hunger and thirst of all humanity was experienced by Jesus on our behalf. He experienced our hunger because all of our unrighteousness was taken on by he, himself. When he uttered “I thirst”, those present interpreted this as physical thirst. And no doubt, anyone suffering the effect of crucifixion would be one severely dehydrated and lead to an intense physical thirst. But I would suggest that at this point in his process of dying, carrying the sin of the world, he would have had a sense of not the reality of separation from the Father, and at that moment, the thirst that can only be quenched by the full and open armed presence of the Father in all his holy love, and in full fellowship was now present, and would consider this thirst as the greater for the obedient, Father- loving and now suffering Jesus. He also uttered “My God why have you abandoned me”. Again this supports the state of Jesus bearing a of us, sinful and rebellious humanity, in himself. This identification with our fallen-ness was also demonstrated powerfully in his baptism by John. At that point John recognised that Jesus had no need to be baptised, yet this obedient act by Jesus was the beginning of his ministry, and showed his willingness to take on our sin, even our imperfect baptism, and then completing this at the cross.
In Jesus’ suffering and death, the dividing wall of hostility, the brick wall curtain that separates us from God was destroyed, and we are made righteous, as a gift. A gift we could never earn or achieve or even hope to achieve, no matter how many prayers, fasts, self giving, self deprivation, acts of repentance, deep water baptisms, or any other attempt at becoming holy we might undertake.
Yes we can experience a hunger for righteousness. How terrible it is to be in the presence of the living God, with nothing but our sin and rebellion, our broken promises, our impure motives, our pretence at goodness unmasked, our human morality now putrid, our self righteousness a worthless whimper. What a blessing to hunger for true righteousness, the presence of God himself, fellowship in his kingdom, the kingdom of the son he loves.
This hunger is a blessing for God himself satisfies it. He satisfies it by sending his only begotten son, that whoever believes in him should not perish but have everlasting life.
