This is not condemning “sleep” (8142) but the tendency to take a nap when there is work to be done. It’s not about sleep. It’s not about “rest” (7901). It’s about laziness.
Sin is often the misuse of blessings God has given us. Knowing become adultery. Appetite become gluttony. Rest becomes sloth. Keep in mind that God was the one who told us to take the seventh day off. This was the Sabbath.
(Hebrews 4:9 KJV) There remaineth therefore a rest to the people of God.The Greek word here transliterates into a form of “sabbath”. God is not only in favor of taking a break, He demands it, but not at the expense of being productive.
So? Take your day off. You need it. God made you that way. But beware of the tendency to eat the whole bag of chips when you only need a few.
