The Bible shows the way to go to heaven, not the way the heavens go.

Different tools for different jobs

We live in an age where we expect our sources of meaning to also be sources of technical instruction. If someone talks about spirituality, shouldn't they also have reliable opinions on science? If a religious tradition speaks to the soul, shouldn't it also explain how the universe works? Galileo's observation cuts through this confusion with elegant clarity: different things have different jobs.

The practical insight here applies far beyond theology. A cookbook teaches you how to make good food, not how to grow crops or run a restaurant. A marriage counselor helps you build intimacy, not manage your finances or treat your anxiety (though all of these touch your life). We suffer needlessly when we expect one source of wisdom to be complete, or when we dismiss something valuable because it doesn't answer every question we have.

What makes this relevant today is how often we swing between extremes. Some people abandon their spiritual frameworks because science contradicts one claim. Others reject scientific findings because they conflict with inherited beliefs. Galileo points to a steadier path: let each domain do what it's actually good at. Your meaning-making systems don't need to be physics textbooks, and physics textbooks won't tell you how to live. Both can be true, and both can matter.
