The price tag is too high. It requires more than following a religion. It requires following Christ. At its heart, Christianity is not a set of beliefs, first principles, propositions. We don't inherit eternal life by being good enough.
Life is a matter of discipleship, of following.
Faith in Jesus is not a set of beliefs about Jesus. It is a willingness to follow Jesus, to be in relationship with Jesus, to be a disciple of Jesus. When I went back to school to seminary, it had been a number of years since college. I knew that graduate school would be a whole different ball game. It was with great fear and trepidation that I forged ahead to seminary.
