I believe that once you belong to the Lord, he pours grace on you continuously. You are connected to him, getting fed at all times. He knows what you need and what's best for you at any moment. He draws you closer and closer to him, strengthening the union. During prayer time after Mass, I now speak less words and think less thoughts. Instead I spend more time just remaining quietly in his holy presence. My mind is so peaceful that it no longer wanders. Sometimes I am so relaxed that I am not sure if I am still awake or asleep, yet somehow I know that the Lord still actively feeds me because I am a branch on his vine.
