Faith is not merely adopting a set of beliefs that you may say in the “Creed”, but a way of life or adherence to that which leads to life.
To what benefit is believing in God without having a relationship with him, obeying and loving Him?
In addition, what is the benefit of believing in eternity and in life after death if one does not prepare for it by repentance, spiritual vigil, and loving God?
And to what benefit is believing in virtues if one does not live them? Therefore there is a big difference between theoretical faith which does not save the soul, and practical faith, the fruits of which are evident in one's life.
