A lot of the things in our daily life, when we talk about them, we have to qualify what we are saying. And there are a whole bunch of things in life which fall into that category. We guess at a lot of things. We hope for a lot of things. We can create a reasonable hypothesis about things.
Faith goes way beyond that hypothetical level.
Faith has to do with the things which we know so well, or which we know so deeply, that we don't have to qualify them. Faith is the level at which we completely trust God. I entrust myself to God, who made all things, the one who was there before it all started, and who will be around long after I am gone. I entrust myself to the God who gave me my life, and who will receive it back again when I die. We can be healers.
