[14] What shall we say then? Is there injustice on God’s part? By no means! [15] For he says to Moses, “I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion.” [16] So then it depends not on human will or exertion, but on God, who has mercy. [17] For the Scripture says to Pharaoh, “For this very purpose I have raised you up, that I might show my power in you, and that my name might be proclaimed in all the earth.” [18] So then he has mercy on whomever he wills, and he hardens whomever he wills.
[19] You will say to me then, “Why does he still find fault? For who can resist his will?” [20] But who are you, O man, to answer back to God? Will what is molded say to its molder, “Why have you made me like this?” [21] Has the potter no right over the clay, to make out of the same lump one vessel for honorable use and another for dishonorable use? [22] What if God, desiring to show his wrath and to make known his power, has endured with much patience vessels of wrath prepared for destruction, [23] in order to make known the riches of his glory for vessels of mercy, which he has prepared beforehand for glory
(Romans 9:14-23 ESV)
The sovereignty of my Lord. It brings me to my knees in thankfulness that He did not raise me up to become a vessel of wrath, but a vessel of His mercy. That indeed, if God had allowed me to continue in my sin, to harden my heart what can my argument be? Cry out that God is unjust?No way, if i want justice than what i deserve is the wrath of God and to be thrown into hell this instant! Who am i, the one created, to challenge and question the work of my Creator? But thanks be to God! that he captured my heart and made me His own, that He had chosen to raise up to be a vessel of mercy, that He would show a wretch like me mercy, O I thank my Lord for His Sovereignty. That He had chose to show mercy onto me. That murderer could have so easily been me, but God called me to be His. Thanks be to God!
Looking at the above scriptures, i would humbly think that the Lord shows mercy to some and to others, He hardens.
[3] But I will harden Pharaoh’s heart, and though I multiply my signs and wonders in the land of Egypt, [4] Pharaoh will not listen to you. Then I will lay my hand on Egypt and bring my hosts, my people the children of Israel, out of the land of Egypt by great acts of judgment.
(Exodus 7:3-4 ESV)
Do not get me wrong, God isn’t the cause of sin, He is a perfect and Holy God and far be it for Him to cause people to sin. But there is a degree of permitting on God’s part that allows sin. I believe the Lord hardens the heart of whose heart has already turned from Him. Jesus promises in John 6:37 that “whoever comes to me I will never cast out”, so here we see that God does not harden the heart of those that earnestly seek Him, He says “seek and you shall find”. We see that Pharaoh was already a wicked man,
[15] But when Pharaoh saw that there was a respite, he hardened his heart and would not listen to them, as the LORD had said.
(Exodus 8:15 ESV)
He had hardened his own heart from the Lord and the Lord had permitted him to do so and He had also done a work of hardening. Such is the sovereignty of God that it is not by human will or effort but by the mercies of God. We can be sure that what he does, He does for the purpose that His will might be done, to glorify Himself as seen in Romans 9- that His power would be shown and His name proclaimed in all the earth.
This humbles me greatly, think about it: God had choose to a wretch like me! now the lyrics ring true in my heart, “amazing grace, how sweet the sound that saved a wretch like me”
