2 things that are definitely true of a faith obstacle: 1-You have to trust God past your current level of understanding (a lot of it just doesn't make sense to you), and 2-You have no way of being certain of the outcome.
As I look out over the college student landscape, I have to be honest and say that I don't see a lot of students taking on God's faith obstacles. As much as students talk about revival, and talk about wanting to see God work supernaturally, many are not willing to invest the faith to see it happen. Instead, many think that by just wanting it, God will respond, or that somehow they deserve to be blessed with God's supernatural provision and response.
It's a sobering thing to truly reckon with the reality that it costs us quite a bit and usually more than we want to give to follow Jesus on a day to day basis.
