    Introducing Practical and Responsible AI

    Artificial intelligence is becoming part of how we work, learn, analyze information, and solve problems. Yet knowing how to use AI effectively involves more than simply asking it a question.

    I’ve been developing a series called Practical and Responsible AI to help people understand how to use AI more effectively while recognizing its capabilities, limitations, and risks.

    The series is intended for both technical and nontechnical readers. My goal is to make the concepts approachable, provide examples that people can try for themselves, and encourage thoughtful use rather than simply promoting the technology.

    What We’ll Explore

    We’ll start with some of the everyday ways AI can help, such as summarizing long documents, making technical information easier to understand, comparing options, and organizing ideas into something useful.

    From there, we’ll look at how to communicate more effectively with AI. Small changes in how we explain a task, describe the audience, or provide context can make a significant difference in the response we receive.

    We’ll also spend time on something I consider especially important: learning to question what AI gives us. A response can sound convincing and still contain mistakes, unsupported assumptions, or missing information. Knowing how to recognize and verify those issues is just as important as knowing how to write a good prompt.

    As the series progresses, we’ll explore responsible use, ways to make AI part of repeatable workflows, and more advanced capabilities such as working with trusted information, specialized AI tools, and agents.

    Each article will focus on a specific concept, usually with a practical example or sample prompt that readers can adapt to their own situations.

    A Principle Throughout the Series

    AI can be a valuable assistant, but it is not a substitute for expertise, verification, or human judgment.

    A well-written prompt can improve the usefulness of a response. It cannot guarantee that the response is correct.

    My hope is that these articles will help readers become more capable and discerning users of AI, whether they are just getting started or already using it regularly.

    This series will be one of several areas of writing on this website, alongside data modeling, work experience, and theology. Each will maintain its own focus, allowing readers to explore the subjects that interest them.

    I’ll continue adding to the series as time and my schedule allow.

    I welcome thoughtful questions, examples, and discussion as the series develops.

  • The Romans Road: The Problem, the Penalty, the Gift, and Our New Life

    The Romans Road: The Problem, the Penalty, the Gift, and Our New Life

    This article brings together five statements from the book of Romans that explain the Gospel. They take us from the problem of sin, through its penalty, to God’s free gift, how that gift is received, and the believer’s new standing in Christ.

    Statement 1: We Have All Sinned

    Romans 3:23

    “For all have sinned and fall short of the glory of God.”

    Who? We all have.

    What have we done? Sinned.

    Where does that leave us? Short of the glory of God.

    Have you ever done anything in your life that you would never tell anyone else?

    Maybe you took your little sister’s treat. Maybe you did drugs. Maybe you took a pencil that didn’t belong to you. Maybe you committed murder. Maybe you yelled at someone in traffic.

    We tend to look at that list and rank the sins from small to large. But Jesus pointed out that sin is a matter of the heart. It only takes one sin to separate us from a holy God.

    Once that relationship is broken, we cannot restore it ourselves. We are the ones who broke it. Restoration has to come from the One we sinned against.

    So where does that leave us?

    Statement 2: The Wages of Sin Is Death

    Romans 6:23

    “For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.”

    We have all sinned. Now let’s talk about the outcome.

    “The wages of sin is death.”

    A wage is something you earn. Romans tells us that what sin earns is death.

    But that can be difficult to understand. Surely not every sin deserves death. Does it?

    About 20 years ago, I had a men’s group leader who gave us an illustration that has stuck with me.

    He said we were going to make smoothies. He brought out ice cream, fruit, candy, and various sweets. We picked what we wanted and put everything into the blender. Each scoop was thoroughly blended until it looked rich and creamy.

    Then he took out a little baggie.

    “Now we’ll just add a little dog poop.”

    It was an almost microscopic piece. He dropped it in, blended everything together, and asked, “Okay, who wants some?”

    There were no takers.

    His point was not that every sin is equally terrible in its earthly consequences. His point was holiness.

    God is perfectly holy. We sometimes look at our lives and compare ourselves with other people: “What I did wasn’t that bad.” But other people aren’t the standard. God is.

    Sin brought death into God’s creation and separated sinful humanity from a holy God. Whether we consider our sins large or small, none of us meets God’s standard.

    Romans 3:23 tells us:

    “All have sinned and fall short of the glory of God.”

    Romans 6:23 tells us what our sin earns:

    Death.

    That is the bad news.

    But Romans 6:23 does not end there.

    Statement 3: The Free Gift of God

    Romans 6:23

    “For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.”

    It is not just a gift. It is a free gift.

    What does that mean?

    It means we cannot earn it. We cannot deserve it. And we cannot repay God for it.

    I was talking with a friend who said he was looking forward to defending his life before the Lord. But we have already seen the problem with that defense: we have all sinned, and what our sin earns is death.

    There is no defense we can offer based upon how good we have been.

    But Romans 6:23 does not stop with what we have earned:

    “But the free gift of God is eternal life in Christ Jesus our Lord.”

    Notice where that eternal life is found: in Christ Jesus.

    Romans 5:8 tells us why:

    “But God shows his love for us in that while we were still sinners, Christ died for us.”

    We could not pay the debt ourselves. Jesus could—and He did.

    That is why the gift is free to us. It was not free because it cost nothing. It is free because Christ paid the price for us.

    The gift is eternal life—not simply life that lasts forever, but life in Christ, reconciled to the God from whom our sin separated us.

    We have seen the problem.

    We have seen the penalty.

    Now we have seen the gift.

    How do we receive it?

    Statement 4: Everyone Who Calls Upon the Lord Will Be Saved

    Romans 10:9–10, 13

    “Because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved.

    For with the heart one believes and is justified, and with the mouth one confesses and is saved.

    For ‘everyone who calls on the name of the Lord will be saved.’”

    Paul talks about two things here: believing in our heart and confessing with our mouth. But these are not two unrelated steps that earn our salvation.

    The confession comes from what we believe.

    Paul expresses this beautifully in 2 Corinthians 4:13:

    “I believed, and so I spoke.”

    Saying a set of words without believing them saves no one. We are not saved because we learned the correct words to say.

    The belief comes from the heart.

    Does that mean we need perfect faith? Perfect understanding? Do we have to understand every doctrine in the Bible before we can be saved?

    Heavens no. None of us would be saved if that were true.

    But we do need to understand the problem we have been talking about:

    We are sinners.

    God is holy.

    Our sin has separated us from Him.

    We cannot fix that problem ourselves.

    Jesus Christ did for us what we could not do for ourselves.

    He died for our sins, and God raised Him from the dead.

    We place our trust in Him.

    Then what we believe in our heart is naturally expressed by our mouth:

    Jesus is Lord.

    That is why Romans 10:13 makes the invitation so wonderfully simple:

    “Everyone who calls on the name of the Lord will be saved.”

    Not everyone who has lived a good enough life.

    Not everyone who has earned it.

    Not everyone who has managed to pay off the debt.

    Everyone who calls upon the Lord.

    The gift is free.

    Christ paid for it.

    We receive it by faith.

    What happens next?

    Statement 5: There Is Now No Condemnation

    Romans 8:1–2

    “There is therefore now no condemnation for those who are in Christ Jesus. For the law of the Spirit of life has set you free in Christ Jesus from the law of sin and death.”

    Those who have trusted in Christ have been justified.

    What does that mean?

    It means we have been made right with God. The penalty for our sin has been paid by Christ.

    Think of a courtroom.

    You have been found guilty of a crime. There is no question about your guilt, and the sentence is death.

    The prosecutor stands and says, “He is guilty. He deserves the sentence.”

    You have no defense.

    But then Christ steps forward and says, “I will pay his penalty.”

    The penalty is paid.

    You are free to go.

    That is the picture I want you to see when Paul says:

    “There is therefore now no condemnation for those who are in Christ Jesus.”

    Notice that Paul does not say there is now less condemnation.

    He does not say we are on probation.

    He does not say there will be no condemnation after we have proven ourselves worthy.

    There is now no condemnation for those who are in Christ Jesus.

    Does that mean we will never sin again? No.

    Does it mean we will never fail? No.

    It means our standing before God has changed.

    We began with:

    “All have sinned.”

    We learned:

    “The wages of sin is death.”

    Then came:

    “The free gift of God is eternal life in Christ Jesus our Lord.”

    We learned that:

    “Everyone who calls on the name of the Lord will be saved.”

    And now we arrive here:

    “There is therefore now no condemnation for those who are in Christ Jesus.”

    For those who have trusted in Christ, that is our new state.

    We are no longer condemned.

    We are in Christ.

    The Question

    The Romans Road does not end merely with information about sin, death, or even salvation. It brings us to a Person: Jesus Christ.

    We cannot repair our relationship with God, earn eternal life, or remove our own condemnation. Christ has done what we could not do. The gift is offered freely, and everyone who calls upon the name of the Lord will be saved.

    The question is not whether we have lived well enough to deserve the gift.

    We have not.

    The question is whether we have placed our trust in Jesus Christ.

  • Welcome

    Welcome to my new blog.

    This is a place for writing about Scripture and the Christian life, prayer and ministry, technology and data, family history, and lessons gathered over a long career. Those subjects may appear unrelated, but each represents an important part of my life and the work I hope to preserve and share.

    My goal is to make complex subjects understandable, distinguish Scripture from my own conclusions, preserve useful sources, and write candidly when thoughtful people disagree.
