I believe the heart of the matter is very simply the following:
In matters of the intellect, do not pretend that conclusions are certain which are not demonstrated or demonstrable.
Indeed this is why we call it faith.
In fact, we all have that God what we are saying, but we have a lot of minds, and a lot of ideas, and thinking about God. It is only just our faith what we are saying, we all have our own faith, and own thinking who will be going to trust on, and we all see, we must know what does this God, and who will be believing on.
