Same Purpose.

"For the scripture saith unto Pharaoh, Even for this same purpose have I raised thee up, that I might shew my power in thee, and that my name might be declared throughout all the earth." Rom 9:17.

Reading through the whole chapter of Romans 9 we see that God has made us for these two reasons;

1. Make His Power known, and
2. Declare( and establish) His Holy name throughout all generations. 

1- To make His Power known.
Power {Dunamis}- a.k.a force,ability,abundance,meaning,might,deed,strength,rule,works,etc.
God's power created the whole heaven and earth, and many do not know anything about it or have experienced it. Our receptors (or sense of perception) changed since the first Adam "ate" of the Tree of the knowledge of good and evil (Gen 3). From then onward man now broadly and generally categorize everything into these subgroups of Good and Evil. Man's world revolves around these two forces of good and evil, and has permeated into everything he does. But should this be the same for the redeemed,the born-again believers?
As believers we have this understanding,that God is Sovereign and answerable to no one: dead or alive. He created everything for a purpose - to show to us of Himself. The fallen man has chosen to experience God in "good and evil" measures. To them fire is either good or bad depending on their circumstance. To us believers everything becomes more radiant and beautiful as we get to know more and more of His Person and His "principles of perfection",that is, His Word. This is His original plan and purpose for man forever,even before the fall. He created us as "vessels of glory" to behold and pour Himself into, for He only is Pure and Holy.

The fall of man brought sin with it and therefore good and evil measures( or should I say the "sin of measuring things of the Holy and True God based on good and evil"?! Just a thought ;), making man into a different vessel - a vessel of wrath and dishonour set for destruction.We came into this world through sin as vessels of wrath, fitted for destruction .
" What if God, willing to shew his wrath, and to make his power known, endured with much longsuffering the vessels of wrath fitted to destruction:" (Rom 9:22).The scriptures says that Pharaoh was raised by God, as a vessel of wrath, a vessel God would pour His wrath into in the demonstration of His Power,while at same time showing His mercy unto the vessels of mercy, the Israeliltes.
From the Throne of judgement, the hardened hearts(that is, the vessels of wrath) will always experience the force of God's power against them, while the believers (that is,the vessels of mercy) will always experience His mercy. We are all vessels God is pouring Himself into, and He answers to no one.Everyone must answer to Him: "Therefore hath he mercy on whom he will have mercy, and whom he will he hardeneth."(Rom 9:18). Check your heart, is it hardened against God? Pharaoh's heart was hardened against God and it led to the destruction of pharaoh and his kingdom.

2- To establish His Holy (fearful) name.
God's demonstration of His power brings His reverent fear into the hearts of men,which should result in the worship and blessings of His Holy name. It's not a complicated demand, but could be if you don't have understanding of the knowledge of Him. Many have received revelations from Him through studying and hearing inspired messages and then have quickly forgotten. No wonder we're seeking for God everywhere but not in our hearts.
Is your heart hardened just like that of pharaoh? After several persuasions and power demonstrations(called plagues), that gradually wrecked the whole economy of Egypt,pharaoh wasn't even moved, and this eventually led to his destruction. [Read Exodus chapter 7 - 12]. Everyone's heart that his hardened against God suffers greatly. Anguish,pain,lack and sorrow is never far from them until they repent. The bible contains many accounts of what God has done, in time past and they are written for us to bring the reverent fear of God into our hearts. Either way you choose, the purpose of God won't change because of anybody.It's forever established in heaven and here on earth.Amen.

In summary,the Purpose of God by election,is for His Holy name sake. To show and demonstrate His Power in the camps of those that hate Him and the Riches of His Glory through His children for the whole world to see and fear Him(God). So therefore are we all Called to do this Work. You part is to accept His call on your life. Are you being raised right?
"And say, Thus saith the Lord GOD; Behold, I am against thee, O Zidon; and I will be glorified in the midst of thee: and they shall know that I am the LORD, when I shall have executed judgments in her, and shall be sanctified in her."(Eze 28:22).
