Is the Christian life that tough?

My eyes have been opened up quite a bit since I learned how to use a computer. I was a very naive person. I have encountered some people who were once Christians who have since denounced Christ. The latest was a pastor who was in the church for many years, I've come to grips with the fact that a few discontents have left the church, but this guy thinks that the church has robbed him of his time. Can you be "robbed" of anything if you do it willingly?
