Values can only be found in God’s glory. They are determined by God who is the creator of all things. All things were created to glorify him. And all things were originally created good. God is good and defines what is good.
We do not live in a dualistic world, meaning, evil is simply a lack of good. Thus, when someone murders an innocent person, evil is not a thing that lives within the murderer, but rather, a lack of good within the murderer. What is good is determined by God. His character is the very definition of good.
When people ask, "Can God logically commit evil?" it's like asking if God can make a rock to heavy for himself to lift or if he can make a squared circle. The answer is no. It's not that he is too powerless to create a rock too heavy even for him to lift, it's that the questioner has given a question that goes against the law of non-contradiction. Therefore, we can conclude, God, being holy and perfect, cannot commit evil because it goes against the law of non-contradiction. If he were able to commit evil (remember this is a lack of good), then he wouldn't be God. One of the requirements of God's character is that he is good.
If the God of Scripture exists, and I believe we have ample reason to believe this is the case, then we can expect that only that which he defines as being good is actually good. Those are the things of value.
