What Are You Thinking?

C.S. Lewis understood that the most decisive battleground of human life is the mind. Long before habits shape behavior or circumstances define outcomes, our thoughts and beliefs quietly form the trajectory of our lives. As Lewis wrote in Mere Christianity, every moral choice we make is not merely an action but a step toward becoming a certain kind of person. Over time, those steps shape the soul itself.

What we repeatedly think, he argued, becomes what we love—and what we love ultimately governs how we live. In this way, belief is never abstract. It is practical, formative, and deeply personal. Our inner dialogue determines whether suffering hardens us or humbles us, whether loss destroys us or redeems us.

Optimism is easy when everything works. Faith is easy when the body is strong and the future feels predictable. But when pain enters—when control is stripped away—we discover that thought is no longer a luxury; it is survival. Lewis himself knew suffering intimately, and he observed that pain does not create belief so much as reveal it. What we truly think about God surfaces when comfort disappears.

Lewis famously wrote that if you aim at heaven, you get earth “thrown in,” but if you aim at earth, you get neither.  That’s pretty awesome…and so true for anyone who has tried both approaches.  Why do I feel so refreshed when I focus on refreshing others?

In the end, what we think shapes who we become, and the type of world we create for ourselves. And who we become determines how we live, suffer, endure—and hope. Thought is not passive. It is the steering wheel of the soul, it’s the rudder of our ship on earth.

In today’s world, it’s too easy to get so caught up in making a living, that we forget to make our life. 

Control your thoughts, control your life.
