Vessel (definition 1, www. Merriam-webster.com)
A. A container (such as a cask, bottle, kettle, cup or bowl) for holding something.
B. A person into whom some quality (such as grace) is infused
The heart is a vessel, by either definition – a container, or the core of a person. Either way, the heart will contain something, be infused by something. If it isn’t God, it will be something else.
Please God, let it be you. Amen.
