God is a person. As a person, God is relational. God reacts based on the actions of individuals and changes as they do. God is very clear this is how He operates. It is simple and common sense:

Exo 20:5 you shall not bow down to them nor serve them. For I, the LORD your God, am a jealous God, visiting the iniquity of the fathers upon the children to the third and fourth generations of those who hate Me,
Exo 20:6 but showing mercy to thousands, to those who love Me and keep My commandments.

The message is: If you love me, I will return your love. If you hate me, I will return your hate.

Not only is this normal behavior for a vast majority of all relationships, but God emphasizes these principles throughout the Bible:

Jer 18:7 The instant I speak concerning a nation and concerning a kingdom, to pluck up, to pull down, and to destroy it,
Jer 18:8 if that nation against whom I have spoken turns from its evil, I will relent of the disaster that I thought to bring upon it.
Jer 18:9 And the instant I speak concerning a nation and concerning a kingdom, to build and to plant it,
Jer 18:10 if it does evil in My sight so that it does not obey My voice, then I will relent concerning the good with which I said I would benefit it.

Here again God stresses that He changes in relation to others. Even if God was going to destroy a people, if that people repents then God will also repent. We see a clear example of that in Jonah. God prophecies destruction, the people repent, and the text states that God repents:

Jon 3:10 Then God saw their works, that they turned from their evil way; and God relented [repented] from the disaster that He had said He would bring upon them, and He did not do it.

God not only operates this way on a national level, but also on a personal level:

Eze 18:25 “Yet you say, ‘The way of the Lord is not fair.’ Hear now, O house of Israel, is it not My way which is fair, and your ways which are not fair?
Eze 18:26 When a righteous man turns away from his righteousness, commits iniquity, and dies in it, it is because of the iniquity which he has done that he dies.
Eze 18:27 Again, when a wicked man turns away from the wickedness which he committed, and does what is lawful and right, he preserves himself alive.
Eze 18:28 Because he considers and turns away from all the transgressions which he committed, he shall surely live; he shall not die.
Eze 18:29 Yet the house of Israel says, ‘The way of the Lord is not fair.’ O house of Israel, is it not My ways which are fair, and your ways which are not fair?

God stresses His fairness. If a righteous man becomes evil, God may kill him. If an evil man becomes righteous, the evil man will be spared.

When God explains to people how He operates, it is: common sense, fair, and very responsive. Theologies which minimize God responding to human beings demean what God says about Himself.
