You are not completely released from your parents, but you are free to be yourself. It puts you in a place where you search things out and examine who you are. College opens an opportunity for people to deal with reality. That is why the gospel is so incredible at college age. It s the most real thing there is.
College is a time to dig in and grow.
A lot of students try to search out God s will and know the future. God s ultimate will for us is that we pursue Him every day and know Him. If that is our goal then we have the freedom of Christ to pursue our desires, and ministry is a part of that. People who see you pursuing something passionately are going to notice and be ministered to.
