Are you tired? There is someone who offers rest, but not any rest, but a true one, the one that the human being needs, and is called God, who is not busy enough not to attend your prayers. He is the good shepherd, and if we trust Him, then we will have peace.
Psalm 23 is a well-known song, possibly even many non-Christian people know that it says “The Lord is my shepherd,” at least that part. And in the churches, well, come on, I think we mostly recite it by heart.
