The optimistic answer is that the role of faith at a Christian college is central. It should affect and fuel all areas of the University. While every class taken may not be a theology class, at a Christian college, Professors will teach classes from the perspective of belief in Christ and the Bible as truth. This can take many forms, such as a discussion of how believers can see God in the course content or how the reading emphasizes the human condition as understood from a biblical perspective, etc. For each subject there are endless ways to connect learning with faith.
As for campus life, the role of faith can look like anything from chapels and dorm bible studies to conversations with friends and peers. Most Christian colleges offer chapels (some make attendance mandatory) and other opportunities for spiritual growth, like clubs or student-led groups that focus on reading the word and applying it to life in general or life at college. Typically, Christian colleges will also have campus ministries or a Christian counseling department available where students can go to speak to someone for help or concerns with their faith or to find opportunities or groups to grow with.
One of the benefits of going to a Christian college is that there is a degree of assurance that those around you are also there to grow spiritually or at least come to understand the faith better. It makes it much easier to find peers who are willing to talk about struggles or testimonies, who are willing to share perspectives on faith and can relate to some of the difficulties that can come with balancing college and faith. At a Christian college, finding accountability and encouragement could be as simple as talking to a classmate or professor, or as traditional as talking to a pastor, or counselor.
