The Psalm is talking to the "servants of the Lord" who specifically "minister by night". I would suppose the literal meaning was the night shift of the temple, but it struck me how many people in my life "minister by night" in the sense of stepping into another's darkness or nightmare every day. The ones who run into the burning houses of life while everyone else is fleeing the scene. Such heroic and precious people.
Well, I love how it directs those people to a beautiful word..."sanctuary". It's the place of safety, presence and peace. Walking with someone in their hell...or dark night of the soul...is so very hard on the heart of the minister as well. They need to have those moments of sanctuary to have their compassionate hearts nurtured and filled.
What a great reminder that the God who crafted the heavens and the earth is that very same God who brings comfort and peace. So, ministers in the night????...know you are seen for your gifts! And, know there is rest for your mercy-driven heart!!!
