Since deeds and works are matters of intention and thought, they are also matters of love and faith to the point that their quality is the quality of their love and faith. That is, it amounts to the same thing whether you talk about our love or about our intentions, whether you talk about our established faith or about our thought, since what we love we also intend, and what we believe we also think. If we love what we believe, we intend it as well and do it to the extent that we can. Anyone can realize that love and faith dwell within our intentions and thought and not outside them, since intent is what is kindled by love and thought is what is enlightened in matters of faith. This means that only people who can think wisely are enlightened; and depending on their enlightenment they think what is true and intend what is true, they believe what is true and love what is true.
We do need to recognize, though, that volition makes us who we are. Thought does so only to the extent that it arises from our volition, while deeds and works come from both. Or in other words, love is what makes us who we are; faith does so only to the extent that it arises from love, and deeds and works come from both. It follows from this that love or intent is the actual person, for the things that come forth belong to the person they come forth from. To come forth is to be produced and presented in a form suited to observation and sight.
We may gather from this what faith is apart from love—no faith at all, only information with no spiritual life in it. The same holds true for deeds apart from love. They are not deeds or works of life at all, only deeds or works of death containing some semblance of life derived from a love of evil and a faith in what is false. This semblance of life is what we call spiritual death.
