There is a lot on confusion on the subject. ..... The core issues that require clarification and clarity are often:
1) That impassibility is not the same as impassivity
Michael Horton writes,
“First, it is important to define what we mean by impassibility. The Greek word
apatheia, because it is used in Stoicism and Christian theology, may easily be misunderstood as referring to the same idea as
impassibility. However, the apathy of indifference at which the Stoic philosopher aimed – immunity to the harm or delight that makes one’s happiness dependent on others – is far from the Christian conception. This difference in meaning is further obscured by the fact that the Latin cognate, passus, is typically understood in the English word passion to refer to emotions generally.[1]

2) That God always is what he is, and does not "react" to circumstances in creation - nor would he ever need to since he knows all things from before the foundation of the world.
3) Thought needs to be given to the concept of what an emotion is, or how it is defined - in relation to its common definition I believe we ought not to ascribe emotions to God.
4)Clearly God "loves" etc. indeed he "is" love - since he is immutable and wholly other from us this love is different from our love, and should be thought about in connection with God's being and will which are as immutable as he is.
5) The use of analogy and anthropopathism should be kept in mind when analyzing individual texts.
Richard Muller writes,
“What is more, in the usages found in Christian tradition, immutability (or, indeed, impassibility, when the term is actually used) in no way implies an absence of relatedness, love, long-suffering, compassion, mercy, and so forth. Impassibility, when attributed to God in the Christian tradition, and specifically, in medieval and Protestant scholastic thought, indicates not a Stoic notion of apatheia, but an absence of mutation, distress, or any other sort of negative
passiones.”
