Using our mental faculties and critical, rational thinking is not meant to undermine our faith, of course, but it can. Some people do reason themselves out of their faith. But for others, critical, rational thinking serves to strengthen their faith. It depends on how the person goes about the questioning process. Paul, Saint Augustine, Martin Luther, C. S. Lewis, and many other great Christian thinkers used reasoning and logic to strengthen their and others’ faith and understanding of doctrine, as well as to help shape the faith and intellectual viewpoints of Christianity.
We can use our intellectual abilities to glorify God and to affirm our faith, just as we can use any of the other skills and talents He has given us. We can use our minds to better love God, as Jesus told us to do. We can also use our intellectual abilities to find the place He has for us in this world, to further our education and understanding of the world, and more. As is the case with all gifts from His hand, He expects us to use the mental abilities He has given us, to invest them wisely, and to allow them to benefit ourselves and others.
