For several years now, I've had the same pre-worship ritual. I close the door to my office and put on my alb and my stole and I pray.
I pray that the preparation I have done for this time of prayer and praise has been good and honourable. I pray that the Spirit will pick up the pieces where I have failed to bring my "A" game. I assure God that I know the Spirit has my back and that I trust in her presence with us all through this time of worship.
Then I use the words of Edwards Hays, saying, "Gracious God, may this act of holiness I am about to perform bring forth from within me more and more personal holiness."
Three deep cleansing breaths, an "Amen", and I'm out the door.
May you and yours be blessed this day.
