You know you have found grace when a great loss occurs and you can say, "God, I'm okay with that." When you can accept that loss without resentment you have somehow transcended this mortal realm.
First there is seeking and with that the dark night which can last days or years. But, at some point the seeking stops. Why? Because when trust sets in the way becomes effortless. It doesn't mean that further progress does not occur, but that it comes as a flow you go with. No struggle. No resistance.
