I have heard a complaint. About some of my preaching and sermons. “It didn’t feed me. I already knew this.”
I have heard this after a sermon on life after death, whose message was: there is life after death.
Obviously, given the complaint, the experience was lacking in some way for the person involved.
The next thought, which I will not accept, is that this means I have failed. I did not fail. A person had an experience that expressed itself in a complaint or recognition of lack. That is all. I can read the most spiritual book, listen to the most enlightened teacher, and still feel “not fed.” This is possible and in fact I too have had such experiences.
So what is missing?
The same thing that is always missing and that is never missing: God.
Someone heard the message that there is life after death and did not feel uplifted by this, did not feel expanded by this, did not feel the hope that this gives. Someone, which also is me on occasion, felt out of touch with God.
The only task that this leaves in this present moment is to feel the presence of God. It is the wish of my life to be of help with this task.

There are no failures, only feedback!
