This week on Theology Simply Profound, Rob and Bob move along on the path with Christian and Hopeful in John Bunyan's, Pilgrim's Progress. On this path, which has proved difficult at times, they find an easier way and they meet Vain-Confidence who is certain this easy way is the way to the Celestial City. However, he meets a disastrous end.

In the incarnation, the eternal Son of God assumed a human nature. He did this without giving up his divinity. He retains his immutability, omniscience, omnipresence, and all the attributes according to his eternal, divine, and necessary existence.

In this episode, we discuss how these two natures relate to the person in the hypostatic union. By looking at Scripture, the Council of Chalcedon, and our confessional tradition, we review an orthodox grammar for speaking about these matters.

An error in the doctrine of God or Christology, however minor it may seem, will inevitably compound as other doctrines are developed. We should always seek to maintain confessional orthodoxy by reviewing the basics from which we never graduate.

Joel Fick continues his introduction to the book of Exodus as he explores a fruitful people, a ferocious king, and the faithful God. Exodus shows us how the people of God will suffer with Christ and be delivered by Christ that they might be glorified in Christ.

In this episode of Theology Simply Profound, Rob and Bob continue to discuss John Bunyan's, The Pilgrim's Progress, where Christian and Hopeful fall into a discussion with By-ends and his companions, Mr. Hold-the-world, Mr. Money-love, and Mr. Save-all.

We turn to pages 202–205 of Vos' book Biblical Theology: Old and New Testaments to continue our discussion of critical theories of prophetism. Vos answers critics who believe that Israel derived its understanding of prophetism from Canaanite religion by focusing our attention upon God's word revealed in history. Contrary to the false prophets, true prophetism is centered on true religion, union and communion with God according to his word.

In this introductory episode to the book of Exodus, Joel Fick explains how important it is to glance backwards and see what God is doing, even as we look forward in time and see how all of God's promises are going to be fulfilled.

The sabbath principle is established in Genesis 2:1–3, immediately upon the completion of God's work of creation. This Sabbath rest principle is a function neither of redemption nor theocracy. It is part of God's creation order. We trace this theme through Scripture with particular attention to worship. Glen Clary recently addressed this subject in a conference for the Amarillo Reformed Fellowship.

Abraham's willingness to offer up his son Isaac at God's command is a remarkable demonstration of obedience. He demonstrates not that he was justified by works, but that the hope of the resurrection fueled his obedience.

In this episode of Theology Simply Profound, Rob and Bob return to The Pilgrim's Progress by John Bunyan. This week we discuss how Faithful's martyrdom served as a witness to Hopeful becoming a believer. Hopeful and Christian begin traveling together and overtake Mr. By-ends for an interesting conversation.

We gather around the table in Wimberley, Texas to discuss the authority of the self-contained Triune God of Scripture. The absolute, self-sufficient God nevertheless established a covenant with man by an act of special providence. In that act, the authority of God's word is diplayed—entirely independently of man's response. Whether Adam obeyed or disobeyed, God's infallible word would be proved.
