Errong Leng | Faith & Code — Reflections on Scripture and Software

保守自己常在神的爱中 这篇关于《犹大书》的讲道提醒我，基督徒的生活并不总是平静安稳的。即使在教会里，也可能出现错误的教导和偏离真理的人。犹大劝勉信徒要记得，使徒早已预告这些事情会发生，因此当我们看到这些情况时，不需要过度震惊或灰心。 让我印象最深的是那句命令： “保守自己常在神的爱中。” 作为基督徒，我们是等候主耶稣基督的怜悯，盼望永生。我们的盼望不是建立在自己有多好，而是建立在基督已经为我们成就的救恩上。同时，我们也需要通过读圣经和祷告不断建立自己的信心。 犹大也提醒我们，对那些疑惑或被误导的人要有怜悯。有些人需要耐心地教导，有些人需要更坚定地劝戒，但无论如何，都要以爱心和怜悯来对待。 行动实践 这一周，我会 每天花一点时间读圣经并祷告 ，求神坚固我的信心，使我常常活在祂的爱中。

Keep yourselves in the love of God This morning's sermon on the Epistle of Jude reminds me that the Christian life is not always easy or peaceful. Even within the church there can be false teaching and people who drift away from the truth. Instead of being surprised or discouraged, Jude tells believers to remember that the apostles already warned this would happen. That helps me realize that spiritual challenges in the church are not new. The part that stood out most to me is the command to “keep yourselves in the love of God.” As Christians, we live waiting for the mercy of Jesus Christ. Our hope is not based on how good we are, but on what Christ has done for us. At the same time, we are called to grow in our faith through simple practices like studying the Bible and praying. Jude also reminds us to show mercy to those who struggle or doubt. Some people need patient teaching, while others need stronger correction. In every case, the attitude should be compassion and ca...

The Call of Faith: The Fig Tree, the Cleansing of the Temple, and the Power of Prayer Today afternoon’s sermon really made me reflect. I have always pictured Jesus as gentle and kind, a comforting Saviour. But I was reminded that He also challenges us, confronts hypocrisy, and calls us to real faith. The cursed fig tree made me think deeply — it’s not really about the tree, but about us. Faith can look good outwardly, but if it bears no fruit, what does it really mean? Love, kindness, patience, joy — am I living them out, or just going through the motions? The cleansing of the temple also challenged me. Worship is not about routine or appearances; it is about honouring God sincerely. Jesus saw the temple defiled by commerce and noise and acted decisively to restore it. This makes me reflect: is my worship focused on God, or distracted by habit, entertainment, or worldly concerns? The power of prayer was another key point. Jesus calls us to pray with faith, to trust that God ...

信仰的呼唤：无花果树、洁净圣殿与祷告的力量 今天下午的讲道让我深受触动。过去我总以为耶稣温和、仁慈，是我们可以依靠的安慰者。但这次我被提醒，祂也会挑战我们，面对虚伪，并呼召我们拥有真正的信仰。 被诅咒的无花果树 让我省思——这不仅仅是关于树，而是关于我自己。外表看似虔诚的信仰，如果没有结出果子，又有什么意义呢？爱、善良、耐心、喜乐，我是否真正在生活中活出来，还是只停留在表面形式？ 洁净圣殿 的故事同样提醒我，敬拜不是例行公事或表面功夫，而是要真心尊崇神。耶稣看到圣殿被商业和嘈杂玷污，祂采取行动，驱赶商人，使圣殿恢复其敬拜的本意。这让我反思，我的敬拜是否专注在神，还是被习惯、娱乐或外界干扰所取代？ 祷告的力量 也是讲道中的重点。耶稣呼召我们要以信心祷告，相信神会回应，并以宽恕的心来生活。真实的信心不是消极等待，而是大胆信靠、怀抱盼望，并从心里结出果子。 这次讲道提醒我，信仰不仅是外在的形式，而是需要真心、果效与生命的改变。我希望自己能够结出真正的属灵果子，活出一颗敬畏神、顺服神、与祂同行的心。

以温柔挽回人 今天早上的信息提醒我，与罪的争战从来不是一个人单独面对的。虽然基督已经打破了罪的权势，但罪的根仍然存在，而我常常在自己的生命中真实地感受到这种张力。有时我轻看自己的问题，有时忽视它们，有时又感到无力挣脱。听到神赐下弟兄姐妹，与我们一同面对这场争战，让我深受安慰。 我也被“温柔挽回”他人的呼召深深触动。真正属灵的关怀不是出于优越感，而是出于谦卑——承认自己的软弱，承认自己同样需要恩典。挽回不是严厉的指责，而是耐心的修补，就像修复一件受损却宝贵的事物。 我也看见自己常常因为犹豫或惧怕而沉默，本该出于爱说话的时候却没有说。爱确实遮盖许多的罪，但有时爱也会为着医治与成长而提出提醒。 最让我得安慰的是基督的心。当我们陷在罪中时，祂不是远离，而是亲近并要恢复我们。我的祷告是，愿神使我既有谦卑的心接受提醒，也有温柔的心去关怀他人。

Gently Restoring One Another This morning’s message reminded me that the struggle against sin is not meant to be fought alone. Though Christ has broken sin’s rule, its roots still remain, and I often feel that tension in my own life. Too easily I downplay my struggles, ignore them, or feel defeated by them. It was comforting to be reminded that God gives us fellow believers to walk alongside us in this battle. I was especially challenged by the call to gently restore others. True spiritual care doesn’t come from superiority, but from humility — recognizing my own weakness and my need for grace. Restoration is not harsh correction, but patient mending, like repairing something precious that has been damaged. I also saw how often fear or hesitation keeps me silent when love should speak. Love does cover many sins, but sometimes love also confronts, for the sake of healing and growth. Most encouraging of all is the heart of Christ. When we are caught in sin, He is not repelled — H...

清楚看见人性 刚刚过去的主日下午的一篇讲道，真的让我停下来好好想想什么是“人”。牧师说我们是“活生生的矛盾体”，我觉得太贴切了。一方面，人类能做惊人的事情——探索太空、进行复杂手术、创造美丽的音乐和艺术。另一方面……我们也会伤害别人，打战争，对亲近的人不友善。真的很乱。 讲道中提到，上帝按照自己的形象创造了我们——原本是好的，能够认识祂、爱祂，并与祂同住。亚当和夏娃在伊甸园里与上帝同行，享受祂的同在。上帝的形象在我们身上，就像一幅原本完美的画，现在有了裂痕。虽然罪败了我们，但这形象依然存在。 我想到了身边的人——邻居、朋友，甚至陌生人。有时我们很容易看到他们的缺点、自私、破碎。但通过上帝的眼睛来看，即使在缺陷中，他们身上仍然有祂的形象。这让我很受触动。 希望是什么？讲道提醒我，上帝还没有放弃我们。祂修复、更新，呼召我们回到与祂的关系里。即使我们觉得自己渺小、软弱或凌乱，上帝仍然看见我们反映祂荣耀的潜力。 听完之后，我心里充满了敬畏和谦卑。敬畏人类在反映上帝时的美好，谦卑面对自己的缺点。但也有希望——因为上帝的恩典能够触及我们每一个人。

Seeing Humanity Clearly I just finished listening to the past Sunday afternoon sermon that really made me pause and think about what it means to be human. The preacher said we are a “living paradox,” and I couldn’t agree more. On one hand, humans do amazing things — explore space, perform complex surgeries, create beautiful music and art. On the other hand… we hurt each other, fight wars, and can be unkind to those closest to us. It’s messy. The sermon talked about how God made us in His image — created good, meant to know Him, love Him, and live with Him. Adam and Eve walked with God in the garden, enjoying His presence. God’s image in us is like a perfect painting that has developed cracks over time. Sin has marred us, but the image is still there. I thought about the people around me — neighbors, friends, even strangers. Sometimes it’s easy to see their flaws, selfishness, and brokenness. But through God’s eyes, even in their imperfections,...

选择忠心，而不是捷径 这篇讲道让我重新思考一件事：当目标看起来是好的时候，“走容易的路”是多么有吸引力。 关于耶稣受试探的信息提醒我，并不是每一个看起来有意义、有价值的机会都应该被接受。 最触动我的是主耶稣那简单却坚定的回应：单单敬拜神。 没有妥协，没有讨价还价，没有通往荣耀的捷径。 祂信靠天父的道路，即使那条路不是立刻得胜，而是先经过苦难。 作为一个普通的基督徒，我常常发现自己想要没有代价的结果—— 想要成长却不愿等待，想要影响力却缺少谦卑，想要安逸却不愿交托。 这篇讲道提醒我，神的国不是靠快速成功建立的，而是建立在忠心与敬拜之上。 忠心也许看起来安静而缓慢，但绝不会徒然。 前面的道路仍然很清楚：敬拜神，信靠祂的时间，并且拒绝那些捷径。

Choosing Faithfulness Over Shortcuts This sermon made me reflect on how tempting the “easy way” can feel — especially when the goal itself seems good. The message about the temptation of Jesus Christ reminded me that not every opportunity is meant to be taken, even when it looks meaningful or impressive. What struck me most was how simple His response was: worship God alone. No negotiation, no compromise, no shortcuts to glory. He trusted the Father’s way, even when that path led through suffering instead of immediate victory. As a regular Christian trying to live faithfully, I see how often I want results without the cost — growth without patience, influence without humility, comfort without surrender. This sermon reminded me that God’s kingdom isn’t built on quick wins. It’s built on devotion. Faithfulness may look quiet and slow, but it is never wasted. The way forward is still the same: worship God, trust His ti...

Righteousness in Christ How often do we try to earn God’s approval with our own goodness? Helping others, going to church, trying to live a “good life”—all of these efforts, though well-intentioned, cannot make us righteous before a perfectly holy God. The Bible tells us that righteousness is not something we can achieve on our own. Abraham, the father of faith, was counted righteous because of his trust in God, not because of his flawless life. Paul, with all his discipline and religious accomplishments, realized that without Christ, all his efforts were worthless in God’s eyes. The good news is this: Christ Himself becomes our righteousness. Salvation is not about personal goodness; it’s about trusting in Jesus, who covers our sins and makes us right before God. Faith is the instrument through which we receive this gift—it’s the hand that reaches out to Christ, not the source of righteousness itself. Once we believe, we are fully accepted in Christ. This freedom allows u...

基督里的义 我们常常尝试靠自己的善行赢得上帝的认可：帮助别人、去教会、努力过“好”的生活——这些努力虽然出于好意，但都无法让我们在完全圣洁的上帝面前称义。 圣经告诉我们，义不是我们自己能达到的。信心之父亚伯拉罕因相信上帝而被算为义，并不是因为他过着完美的生活。保罗拥有极高的纪律和宗教成就，却意识到，没有基督，他的一切努力在上帝眼中都是无价值的。 好消息是： 基督自己成为我们的义 。救恩不是靠个人的善行，而是信靠耶稣，他为我们担当罪，使我们在上帝面前称义。信心是我们接受这一恩典的工具——是伸出的手，而不是义本身的来源。 一旦我们相信，我们就在基督里完全被接纳。这自由让我们顺服上帝，不是为了赢得认可，而是出于爱与感恩。每一件善行、每一次服事，都是源于我们已经在基督里得到的义，而不是为了争取称义。 要点总结： 义唯有基督而来。 信心是接受义的途径，而非义的来源。 人的努力无法在上帝面前称义。 在基督里生活带来自由、爱与荣耀上帝的渴望。 今天，让我们安息在这个真理里：我们在上帝眼中的接纳，不取决于我们做了什么，而是基于基督已经为我们成就的一切。

When Warning Is Love The sermon began with a strong declaration from the book of Jude: “Woe to them.” The message unfolded around one central truth—our spiritual direction matters, and the path we walk ultimately reveals where we are headed. Through examples from history, images from nature, and references to ancient writings, the sermon kept returning to the same point: what appears appealing, easy, or harmless is not always life-giving. Discernment is necessary, even in places that feel familiar and safe. One idea that stayed with me was the warning about hidden danger. Not every influence that feels encouraging or comfortable actually leads toward spiritual growth. Some voices sound pleasant but gradually shift our focus away from what is true. This raised simple but honest questions for reflection: Is faith in my life a habit or a living reality? Do I welcome correction, or only affirmation? Am I growing, or merely maintaining appearances? The sermon also used viv...

当警告也是一种爱 这次讲道从犹大书的一句严肃宣告开始：“他们有祸了。”整段信息围绕一个核心展开——人所走的道路，最终都会显明方向与结局。 讲员从历史人物、自然图像和古代文献三个角度，一次次回到同一个重点：远离神的生命，看起来可能吸引人、轻松甚至合理，但最终是空的，也是危险的。 让我印象最深的是关于“隐藏危险”的提醒。那些看起来没有问题、甚至让人感觉舒服的声音，并不一定真正带来生命。有些影响不会立刻显出破坏力，却会慢慢让人偏离方向。 这让我开始反思：信仰对我来说，是习惯，还是生命？是外在参与，还是内在真实？我是否愿意接受提醒，还是只愿听让人轻松的话？ 讲道也用了许多自然界的比喻：没有雨的云、不结果子的树、漂流不定的星。这些画面都指向一个共同点——外表存在，却没有真正的生命供应。听到这里，很难不问自己：我的生命有没有带来一点真实的果子？ 关于审判的信息听起来不轻松，但整篇信息给我的感受不是压迫，而是认真。真正关心人的提醒，不只是安慰，也包含警醒。因为如果方向错了，再轻松的路也不会带到正确的地方。 这次听道留下的一个简单祷告是：愿意被提醒，愿意被修正，也愿意继续走在正确的方向上。 信仰不是一次决定，而是每天的道路。

一次数据清理引发的教训：缺失外键索引导致 DELETE 性能问题 最近在做一次数据清理（data purge）时，我遇到了一个之前没有预料到的问题。 从业务逻辑上看，这只是一个很普通的 DELETE 操作，根据条件删除历史数据而已。 但实际执行时， DELETE 语句几乎卡住了 。 没有报错，看起来也在运行，但迟迟没有完成。 问题出在哪里？ 在 DBA 的帮助下，我们开始从数据库层面分析这个问题。 最终发现，真正的原因是： 部分外键（Foreign Key）字段缺少对应的索引。 在 Oracle 中，当对父表执行 DELETE 操作时，数据库需要检查子表中是否存在 引用该记录的外键数据。 如果外键列没有索引，Oracle 就只能对子表做全表扫描。 当数据量变大时，这种全表扫描会极大地拖慢 DELETE 操作， 甚至导致长时间锁表，看起来就像 SQL “卡住”了一样。 解决方案 在确认问题后，我们为所有缺失的外键字段补充了索引（涉及多个关联表）。 效果非常明显： DELETE 操作执行速度大幅提升 锁定时间明显缩短 数据库整体负载显著下降 SQL 没变，数据没变，只是补了索引，结果却完全不同。 如何定位缺失的外键索引 DBA 使用下面的 SQL 来检查哪些外键约束没有对应的索引。 以下示例中，schema 名、表名和索引名均已做匿名处理。 WITH fk_constraints AS ( SELECT c.table_name, c.constraint_name AS fk_name, LISTAGG(c.column_name, ', ') WITHIN GROUP (ORDER BY c.position) AS fk_columns FROM dba_cons_columns c JOIN dba_constraints k ON k.constraint_name = c.constraint_name WHERE k...
