So then it depends not on human will or exertion, but on God, who has mercy
Joshua 11:20
For it was the Lord’s doing to harden their hearts that they should come against Israel in battle, in order that they should be devoted to destruction and should receive no mercy but be destroyed, just as the Lord commanded Moses.
Exodus 4:21
And the Lord said to Moses, “When you go back to Egypt, see that you do before Pharaoh all the miracles that I have put in your power. But I will harden his heart, so that he will not let the people go.
Deuteronomy 2:30
But Sihon the king of Heshbon would not let us pass by him, for the Lord your God hardened his spirit and made his heart obstinate, that he might give him into your hand, as he is this day
Romans 9:15
What shall we say then? Is there injustice on God’s part? By no means! For he says to Moses, “I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion.” So then it depends not on human will or exertion, but on God, who has mercy. 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.” So then he has mercy on whomever he wills, and he hardens whomever he wills.
You will say to me then, “Why does he still find fault? For who can resist his will?” 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?” 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? 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, in order to make known the riches of his glory for vessels of mercy, which he has prepared beforehand for glory— even us whom he has called, not from the Jews only but also from the Gentiles? As indeed he says in Hosea,
“Those who were not my people I will call ‘my people,’
and her who was not beloved I will call ‘beloved. ’”
“And in the very place where it was said to them, ‘You are not my people,’
there they will be called ‘sons of the living God.
When Joshua went through the land, obeying God, and destroying all that was living it says that God had hardened the hearts of these people in order that they would be devoted to destruction. I don’t know about you but when I think about how we are living in a time of grace and mercy we often forget about God’s sovereignty, purpose, and plan that in the past included hardening entire nation’s hearts. I read this and wonder what it must would like to have your heart hardened by God and meant for the single purpose of destruction. I have the human thought of “is this fair”??? We can not put our thoughts above God’s. Scripture says our thoughts are not God’s thoughts. I am also so thankful for Romans where Paul addressed this issue of fairness. Man says: “why does He find fault”?, “Who can resist His will”? Why have you made me like this”? Paul continues with who is man that he should question God. The creator can do what He pleases for the purpose He determines without needing our approval or understanding. All I can say is that I am so thankful God softened my heart to hear His calling for the need of redemption, forgiveness, and salvation. Do not neglect His salvation plan and purpose for your life.
