People, especially unbelievers, often raise the question: Why God is required to be praised? Isn’t it antinatural to require a praise of Himself?
When doing mathematics, we want to get familiarized with some math object. Often one of the most important question we ask about an object is “How big is it?”
It is natural for a mathematician to describe how big is an object (such as a function). For example, when we have an exponential function, we understand that it is very big. It is not antinatural (as atheists think) in any way.
God is very very big. So He is worthy of praise, that is of describing how big He is.
When we praise God in a correct way (as guided by Bible and Holy Spirit), we are doing mathematics.
