You were preaching without the sacraments and were surprised when you found you had come back to yourself afterwards.

         You are building the Spirit of God in you so you are now able to preach in the Spirit whether you partake of holy communion or not, but the Lord would rather you would continue partaking.

         By returning to yourself, you know you had left yourself and entered into the Spirit of the Word you were preaching. You had become the new man temporarily.

         Keep up the good work. We are to enter into Christ up through the flaming sword of the Spirit. Then we know we are his ministers.
