Reformed Perspective on On Golfing

The first time I heard of a theological discourse on playing golf, was from Stephen Tong in one of his lectures (on Creation I think). It was brief. It was Nay, when someone invited him to a golf course. It's destruction of nature for the pleasure of a few rich men.

Here, I am doing a deeper digging after seeing a few posts on Facebook of Christian folks enjoying their golf games.

This is a survey only on golf. Not a generalization of sports nor how to use sabbath.

Golf began as gambling historically, A Scottish origin 1500s. Its history was not a good start if you consider the 8th & 10th commandment (do not steal, covet). Possibly fostering unspiritual rage: Induces a pathological obsession with controlling every microscopic variable—the grain of the grass, the speed of the green, the exact angle of a club face.

It's more of an entertainment than any other function.

The general golf course would break Genesis 2:15 - destruction of God's creation for mere entertainment is sinful. Violation of biblical stewardship for indulgent luxury.

Wastefulness of water for the green drains local communities.

Waste of time: Golf window - length of time (4-5 hours in a single round).

Waste of space: Golf demands private, curated fiefdoms.

Chemical pesticides poisons nature.

Reshaping large landscape for vanity.

Solitary delusion - It's not a spiritual experience in solitude as some golfers would argue, but more of a cult (worship) of the self, in an artificial "Eden".

Last but not least, golf is one of the few sports I see keeping fat people.

Puritan principles on Leisure - Readings by Google AI:

"Directions About Sports and Recreations" by Richard Baxter: Found within his massive Christian Directory, this is the definitive Puritan text on leisure. Baxter carefully outlines which sports are permissible and when they become sinful, arguing that leisure should restore vigor, not exhaust the mind or drain one's resources. [1, 2, 3]
The Redemption of Time by Richard Baxter: This treatise emphasizes the stewardship of time, warning believers against worldly distractions, idle chatter, and purposeless entertainment. You can study the full context of his works via the Practical Works of Richard Baxter Index on the Christian Classics Ethereal Library. [1, 2]
The Saints' Everlasting Rest by Richard Baxter: While primarily focused on eternal life, this work frequently contrasts earthly, fleeting pleasures with the ultimate, perfect rest found in God. [1, 2]

Successes of Men

After watching the miniseries Who is Erin Carter? (2023) on Netflix, I thought to myself, you know, the successes of man, whether achieved legally or illegally, are actually the same thing when viewed in light of Genesis 11, 2Timothy 3 (particularly 2Tim 3:5).

The glory is for the self, not for God. Men who call themselves Christians may some of them utter the password: "Glory be to God" but everyone around them sees there's no giving glory to God but themselves. Some men would be more honest, not daring to invoke God's name like that, but still try to prove themselves, in order to keep their "Christian" title or just to have some kind of humble moral diploma stamped in their lives, would donate to charity, volunteer at soup kitchen, host small group Bible study at their homes, becoming pastors. Nevertheless, they do not truly care about the Gospel. The Gospel is a tract for them to keep in their own pockets as a just in case that they could take the tract out in Heaven as evidence of their salvation.

No, those who look after themselves, they do not desire to live with God. They prefer God as only the source of their blessings, not the Creator, not the Father whom they would have personal relationship with.

These, I have no interest to talk to about religion or faith. I am only interested to talk about the Bible, about God, to non-Christians and those who live a Gospel-centered life. Not those who do "Christian" things (i.e. going to church, joining/hosting Bible study groups, etc.) yet are selfish. For they are succeeding in their own peril, like the show's (Who is Erin Carter) depiction of the West, that a mother, Lena (the West) has reached a depravity, despite her ability to love, must give up the daughter she love. And someone else (Kate/Erin) who has adapted to her culture is now apt to take over the role of motherhood for the daughter (Harper). Their love for "Christian things" is futile. God will use it only to their own peril, for the benefit of the others who truly

All of a sudden came across this math quiz on Facebook and I just had to prove it geometrically, Sum of natural numbers = sqrt of sum of natural cubes (Nicomachus's Theorem: first proved by the ancient Greek mathematician Nicomachus of Gerasa around 100 CE):

There's a whole history of this. But basically standard geometric proof is this:

How does the Right demonize the others? By saying things like "But I think what that really comes down to is that these cartels have zero value for human life" @46:59 in this interview by Allie Beth Stuckey with her brother Justin Simmons. It's a failure in understanding total depravity (by redefining it as absolute/utter depravity):

Received my modern guitar from this Chinese (Guangzhou) instrument manufacturing company called Donner which has gained popularity. This is a Donner Hush-I Guitar. Ordered from TEMU, but it's shipped from Bordentown, NJ which took only about 2 days. First test seems great: Sound quality, look and feel. Specifically, the action. Action distance had been a horrible experience for me for my previous guitars.

5/31/2026 Sunday

Speaking to Wayne and Tina, and Carol made me realize that Crossroads may actually have an unhealthy split of faith and work. That if you want theology, you've got to go to a special program; ordinary church life is just for the non-theological members because pastors' sermons are enough. Some of them appear to have this idea that you become member so that you get taken care of by an elder. This is such an inverse of the truth: The elder cares for all who are welcomed until they love becoming members.

I also notice that American Christians to love to chat about non-personal matters, like how Feeding Hands work; rather than anything related to them personally. So basically, anything you can get from ChatGPT A.I. I have to redirect them back to something personal, subtly.

Pastor David Lee's sermon on 1 Samuel 3:1-21 made him bring up how he has this guy friend whom he chats with daily even more than his own wife so to speak until his friend didn't pick up his call which relates to verse 3 when God's words were rare - God's silence. It's interesting correlation, but I would pursue that verse more inquisitively, that "rare", "not many", do not mean total silence.

Jews against Zionists

It seems like there's quite an active movement of Jewish groups in New York who are pro-Palestine.

One such viral movement I've seen online is this Neturei Karta (an ultra-Orthodox sect based in Brooklyn). I don't know if I'd ever come across these live in New York City. I might have briefly brushed by them without knowing it.

Google AI: Neturei Karta is an ultra-Orthodox, anti-Zionist Jewish sect formed in Jerusalem in 1938. They actively campaign for the complete dismantling of the State of Israel, believing Jewish sovereignty over the land is forbidden by the Torah prior to the arrival of the Messiah. Their Messianic Rule = without human intervention. They adhere to highly traditional, insular, and socially conservative lifestyles. Neturei Karta is considered a radical fringe movement that does not represent mainstream Judaism. They often carry signs and Palestinian flags to project the image of "Jews against Israel".

Other similar Jewish groups:
Satmar Hasidim, Jewish Voice for Peace (JVP) NYC, Jews for Racial and Economic Justice (JFREJ, a large progressive Jewish grassroots org), Malkhut in Western Queens (intergenerational Jewish spiritual community serving Western Queens, including Long Island City, Astoria, Jackson Heights, and Sunnyside. Led by Rabbi Rachel Goldenberg).

I've also learned that the most popular Brooklyn group, the Chabad-Lubavitch (popularized by their 7th and final Rebbe, Rebbe, Rabbi Menachem Mendel Schneerson (1902–1994) who was even considered by some followers as the Messiah), is against Palestine. This group love to do outreach (Kiruv) looking for Jews on the streets, which most other conservative Jews despised as they prefer isolation like the Amish. Chabad is considered right-wing politically.

Trump's Aliens.gov

So Trump is turning the immigration policy into some kind of show biz. by word play with "ALIENS". Perhaps this has something to do with the release of UFO classified files earlier.

Nonetheless, I do find their https://aliens.gov map of "illegal alien" crimes in USA interesting, I was able to grab the iframe and paste it here:

The 3 Most Important Functions of a Church

Worship, Fellowship, Evangelization. I believe anything (i.e. networking, charity, fun, supporting missions, etc.) that is brought up higher than these three, would be the downfall of a church even if she can last a long time and increase in number.
