Like CliffsNotes, Sunday mornings are not enough to understand the deep truths of God. 

Quote Source – Jeff Hilles

CliffsNotes were built for one purpose: get the gist without doing the reading. Know enough to pass the quiz, sound informed at the lunch table, move on with your day. Nobody ever closed a CliffsNotes pamphlet and said they understood Dostoevsky. They understood the plot. Those are not the same thing.

The same shortcut shows up in a lot of Christian lives, and it’s worth being honest about it. An hour on Sunday, maybe a sermon podcast on the drive to work, and that’s the whole diet for the week. You walk away with the highlights: sin is real, grace covers it, love your neighbor. All true. None of it false. But a highlight reel was never meant to be the whole meal.

A Church Full of Infants

Paul ran into this exact wall with the Corinthians. He had things to teach them, deep things, and he couldn’t get there, because they weren’t ready to receive it. “I fed you with milk, not solid food, for you were not ready for it. And even now you are not yet ready.” That is not a compliment. It is a diagnosis. A church that only shows up once a week stays on milk by default, no matter how good the preaching is on Sunday, because one meal a week will not grow a person past infancy in anything.

Trained by Constant Practice

The writer of Hebrews describes what actually moves a believer from milk to solid food, and it isn’t attendance. It’s repetition, over time, in the ordinary days between Sundays.

For though by this time you ought to be teachers, you need someone to teach you again the basic principles of the oracles of God. You need milk, not solid food, for everyone who lives on milk is unskilled in the word of righteousness, since he is a child. But solid food is for the mature, for those who have their powers of discernment trained by constant practice to distinguish good from evil. [Hebrews 5:12-14]

Notice the word “trained.” Not gifted, not stumbled into, trained – the way a muscle is trained, through use, Monday through Saturday, long before anyone else is watching. Discernment doesn’t arrive because a sermon was good. It arrives because a person kept showing up to the text on ordinary Tuesdays when nothing felt urgent.

What the Rest of the Week Is For

The blessed man in the Psalms isn’t described as the one who never misses a service. He’s the one whose “delight is in the law of the LORD, and on his law he meditates day and night.” Day and night. That’s the picture Scripture keeps giving – not a weekly appointment but a daily appetite, the kind that reaches for the Word the way a hungry person reaches for food without being told to.

None of this makes Sunday worship optional. Corporate worship, the preached Word, the Lord’s Table, other believers speaking truth into your life – none of that is a shortcut to skip. It’s the gathering that Hebrews itself tells us not to neglect. But it was always meant to be the anchor for a week of pursuit, not the substitute for it. James put it plainly enough: be “doers of the Word, and not hearers only,” which assumes you’ve actually got the word in front of you most days, not once a week.

God did not write a pamphlet. He wrote sixty-six books across centuries, poetry and law and letters and prophecy, meant to be lived with, argued with, returned to for a lifetime. Sunday mornings point you toward that depth. They were never built to deliver it on their own.

Editor Comment: In a culture of highlight reels and quick takes, this quote pushes back against reducing faith to a once-a-week transaction.
