Charles Spurgeon Commentary John 2:7

"Jesus saith unto them, Fill the waterpots with water. And they filled them up to the brim." — John 2:7 (ASV)

There was no fear of anything but water being there: They filled them up to the brim. They obeyed Christ to the letter. If Christ says to you, "Fill the waterpots with water," fill them up to the brim. Never cut down his commandments; carry them out as far as the largest interpretation can go.

When you are instructed to believe in him, believe in him up to the brim. When you are told to love him, love him up to the brim. When you are commanded to serve him, serve him up to the brim.
