So, everything that students experience on a secular college campus is here. The difference is that hopefully, the administration/faculty/staff handle it from a Christo-centric perspective. More times than not that is the case, yet even that isn't always guaranteed to happen.
Students struggle with porn, drug addictions, from parental abuse, depression, cutting, gender identity, lawlessness, drinking, stealing, hypocrisy, legalism, arrogance, materialism, greed, perfectionism, doubt, premarital sex etc. Yes, even students from Christian homes. We want to model following Jesus to our students, but parents must remember that the school environment is not Jesus the Messiah. It doesn't save their students. Each student has the responsibility to follow Jesus. The school is not going to follow Jesus for them.
And while I think a Christian university is a wonderful thing for many, for some it is more damaging than a secular institution. For some, being at a secular university is better than being at a Christian one. Deciding whether or not to send your child to a Christian university is a process that requires discernment.
