Is God Altruistic? Is God Happy?

[Acrobat]

God doesn't have emotions, at least not in the way we speak of emotions, which result as a reactions to things, like seeing a newborn baby, or someone spitting on you. God is unchanging, so it would be false to say God feels one thing, then feels something different later on, etc.

We might use expressions that imply God has emotions like we do, but these are to be taken metaphorically, as a result of the limits of our language in our expressions about God. 

God's charachreristics  like Goodness Love, are statements about God's being, what he embodies. An expression like God hates sin, can be understand as sins reaction to God's love, like an objects reactions to being in close proximity to the sun, which implies not a change in the nature of the sun, just the object itself. 

When speaking of God natures an orthodox believer is referring to his eternal, unchanging nature.

It sounds like you are saying God cannot be pleased because God does not have emotions. Pleasure is an emotion. If you cannot please this authoritarian NO MATTER WHAT YOU DO, then why bother trying?

How does sin affect God?

God simply cannot be omniscient if God has no emotions because emotional intelligence is a thing. If God does not have emotions then it necessarily follows that God cannot have emotional intelligence. Without that intelligence omniscience is not obtainable. It means humans are better than God because we do have emotional intelligence. That's why when we worship we want God to be pleased so He doesn't squish us because He is pissed off.

e·mo·tion·al in·tel·li·gence
noun
noun: emotional intelligence

   the capacity to be aware of, control, and express one's emotions, and to handle interpersonal relationships judiciously and empathetically.

I think it's perfectly fine to say things like God is pleased when we do his will, or when we do good, or are kind, etc. and displeased when we doing things against his will, do wrong, etc...

It's not fine we take these expression to their literal ends, implying God feels pleasure one minute, and displeasure another minute, or that his nature changes, contingent on our actions, or in some way negates his essential properties. God is not contingent on us, we are contingent on him. God being eternal and omniscient, also begs the question of when was God displeased or pleased with our actions only after they occurred, or in his foreknowledge of it occurring, which he always knew?

God isn't a being like finite beings, subject to the finite changes of the universes and human lives. So statements like God's displeasure and pleasure can't be viewed as we might say of finite beings. So displeasure and pleasure are in essence the impact of Gods essential and unchanging nature on us, like the impact of the heat from the sun on an object. To borrow the sun analogy, we might say that Gods Good and Loving nature, allows objects reflective of goodness and love to draw near it, and objects not reflective of goodness or love to burn when near it. Like the sun God's nature need not change, but his nature impacts the objects not himself.

You make it out like God is a rock outside of our universe with your stance. Scripture is clear that God has emotions. Otherwise you have to rule out His Love. You are conflating Unchanging with unmoved by connotation at the least.

It kind of depends of how you're defining emotions, typically when speaking of emotions we're speaking of emotions in a finite sense, which is difficult to apply to non-finite being. 

It's also important to realize, that in the NT God is Love. This doesn't mean god is an emotion, It means Love is a form of being, not an emotion.

Love is essentially who God is is, it's not something god gives or extends, like a helping hand. Love is the object, not an extension of an object. 

We might express god's essential nature in in variety of finite expressions, but this is only because of the limits of our language, that we have to be mindful not to extend too literally, or else you turn God into a finite, and contingent being like ourselves.

Maybe I'm reading you wrong, but doesn't the verse imply that God ISN'T affected or changed in this way? It says “For I the Lord do not change."

I was referring to the other verse in Malachi: "“Yet I have loved Jacob but Esau I have hated."
