We can't be a Christian if we are not willing to live by faith because faith is the heart of Christian living. In fact, the Bible says that without faith it is impossible to please God. Of course, different people can have different concepts of what faith is. Moreover,  just because a person prays to God or attends church regularly or even studies the Bible does not mean he has the kind of faith that the Bible commands us to have. In this very practical sermon, Evangelist explains what biblical faith is, and how it manifests itself in a believer's life.
