You're are familiar with the childhood prayer "Now I lay me down to sleep, " but I was little surprised to learn that it is a shortened version of an Old English prayer, which goes like this:

Matthew, Mark, Luke, and John,
bless the bed that I lie on.
Before I lay me down to sleep,
I give my soul to Christ to keep.

Four corners to my bed,
four angels there aspread,
two to foot, and two to head,
and two to carry me when I'm dead.

I go by sea, I go by land,
the Lord made me by his right hand.
If any danger comes to me,
Sweet Jesus Christ, deliver me.

He's the branch, and I'm the flower,
pray God send me a happy hour.
And if I die before I wake,
I pray that Christ my soul will take.

The prayer has an important refrain, that Christ is the keeper, the caretaker of our soul. And, when we slip into the unconsciousness of the night I suppose, on a daily bases, we are never nearer death. It was out of this fear of sleep that this prayer was written. At night, when we are vulnerable, we want someone watching over us. So, we prepare ourselves with a prayer: If I should die before I wake... Our text this morning asks us to be prepared, to be dressed ready for service. We are to keep our lamps burning for we do not know when our Lord returns.
