The Bible and the Cross

This episode of Theology Simply Profound brings our reading of J. Gresham Machen’s final three audio addresses to a close. This address, “The Bible and the Cross,” would have aired on December 27, 1936. Machen would not finish this series of radio addresses on the atonement. Just five days later on January 1, 1937, he would succumb to pneumonia dying in the Lord.

And so, this series closes so abruptly as life seems to do so very often. With the words, “Isn’t the Reformed faith grand?” and “So thankful for active obedience of Christ. No hope without it,” Machen departed in peace.

The Active Obedience of Christ

This week’s Theology Simply Profound provides another reading from the works of J. Gresham Machen. Since we’ve begun a series on the Biblical teaching of the atonement, Bob is reading Machen’s, “The Active Obedience of Christ.” This was delivered on December 20, 1936 as part of a series of radio addresses given shortly before Machen’s death on January 1, 1937


This week on Theology Simply Profound, Rob and Bob continue their new series of discussions on the doctrine of the atonement. In this episode we talk about the concept of redemption. What is redemption? What is the relationship between redemption and the wrath of God? What is the cost of redemption? How does redemption relate to atonement?

The Doctrine of the Atonement

With Rob nursing a cold, this week’s Theology Simply Profound provides another reading from the works of J. Gresham Machen. Since we’ve begun a series on the Biblical teaching of the atonement, Bob is reading Machen’s, “The Doctrine of the Atonement.” This was from a series of radio addresses given shortly before Machen’s death on January 1, 1937.

The Wrath of God and the Need for the Atonement

This week on Theology Simply Profound, Rob and Bob begin a new series of discussions on the topic of the atonement. In this episode we talk about the wrath of God and mankind’s need for an escape from the wrath of God in the first place. Why an atonement? Why is there a need for an atonement?

Honoring the Elderly

The Rev. Brian L. De Jong, pastor of Grace Presbyterian Church in Sheboygan, Wisconsin, joins Bob and Rob this week on Theology Simply Profound to discuss his new book, Honoring the Elderly: A Christian’s Duty to Aging ParentsMr. De Jong explains the importance of thinking through difficult and complex issues related to how Christians are to honor their aging parents.



We are glad for this opportunity to present ourselves to you, and we very much hope you will come to one of our services so that we can get to know you face-to-face. Westminster is a congregation of people of all ages and various walks of life who are finding out just how good it is to be in a relationship with Jesus Christ. We are all imperfect people, and Westminster certainly is no perfect church. But since we are put right with God through Jesus’ actions and not our own, we can admit our imperfections and accept each other as we are. Step by step, we are making our way by grace toward a celestial city that makes our dear Chicagoland at its best seem drab by comparison.

We are easy to get to, since our building is located virtually on the corner of the Stevenson (I-55) and the Tri-State (I-294)! Feel free to give us a call (708-784-9601), send us an email at info @ westminsteropc . org, or let us know if we can be of help in any particular way. We hope that the information on this site is helpful to you.

Theology Simply Profound

  • Very edifying and thought-provoking
    October 21, 2017 by Carl Gobelman from United States

    I was turned onto these guys by an elder in my church and I haven’t regretted a single moment. TSP is one of my go-to podcasts that I look forward to every week. Doctrinally sound and confessionally minded. If you want solid Reformed content, look no further.

  • Great and informing podcast!
    August 16, 2017 by Cary Gephart from United States

    Love the banter between these two guys but also the well-informed discussions they have about a variety of biblical topics. Keep up the good work guys! P.S. Rob's wife is my kids principle. Providence Christian Academy rocks!!!

  • Love it!
    May 26, 2017 by 184748486993 from United States

    The hosts are amicable to the brethren and informative concerning reformed theology. I learn something new every episode!

  • A Real Treasure
    May 2, 2017 by Lord Lacey from United States

    I found this Podcast through Reformed Forum/Christ the Center. I have listened pretty regularly for a while now. I thought the Revelation Series was enjoyable and well done. I used it as a supplement to my study of the book. The Dispensational Series was a pure joy to listen. As a Reformed Presbyterian I see most things through the same lense as these gentleman but I do think they do a nice job of presenting both sides of a certain topic. I look forward to future stuff from TSP. Keep up the good work gentleman.

  • Buckle up.

    I came for an explanation of dispensationalism and got a thorough series on the nitty gritty details of this theology and its history. I consider myself a bit of an expert now... I also especially enjoyed the podcasts on the lives of Abraham and Noah. Thanks Rob + Bob!

  • Simply Profound Indeed!
    November 2, 2016 by AngelMendezJr from United States

    I love theology and quite honestly, every Believer should. It is, after all, the study of God. But if you love Covenantal Theology, as opposed to Dispensational Theology, then you'll absolutely be helped and stretched by this podcast. Even if you hold to Dispensationalism, download these episodes and learn what the "other side" believes. And if you don't know what either of these two theologies are...well then you too will be in for a treat!

  • Thrilled to have stumbled upon!
    August 23, 2016 by marciw7 from United States

    I was searching for Wayne Grudem's systematic theology teaching and clicked on this and I'm thankful I did. Coming from 40 years of dispensational teaching, the episodes that compared it with covenant theology really opened my eyes. Love the conversational style. Highly recommend!

  • If you are interested in Reformed theology...
    August 13, 2016 by Erame from United States

    A great podcast, especially if you are into The White Horse Inn and Reformed Forum podcasts. Very conversational and accessable yet rich. The series on Dispensationalism is especially helpful. The hosts carefully unpack Dispensationalism and show how it differs from Reformed covanental understanding of the Bible. The episodes are a bit on the longer side, so make sure you have the time to listen carefully; it's worth it.

  • very good
    August 9, 2016 by bjorgsd from United States

    The series on Dispensationalism is very educational. The hosts did not attack or put it down, but tried to explain how each side would present itself to provide us a basis for dialog.

  • Great discussions
    August 6, 2016 by PeteTrane from United States

    I really like this podcast especially their series on dispensationalism. Its very charitable and educational, even for a reforming Christian coming out of that system.

Paul’s Prison Proclamation

This episode of Theology Simply Profound brings our discussion of the Book of Acts to a close. Paul is under house arrest welcoming all who come to him “proclaiming the kingdom of God and teaching about the Lord Jesus Christ with all boldness and without hindrance.” We discuss Paul’s arrival in Rome, his reception by the Jews, and his proclamation of the kingdom of God.

Our apologies for the poor audio quality for the first 10 minutes or so…a few technical difficulties.

What is Faith?

On this week’s episode of Theology Simply Profound, from Acts 28, Rob and Bob discuss everything from snake handling to saving faith… in reality, the discussion lands primarily on the nature of faith. How does saving faith differ from the belief that UFOs will one day arrive to wisp the faithful away to a better place? Hmm. Essentially, is the faith of a Christian the same kind of faith we find in a cult?
