For the second week of Core, hosts Greg and Nathan tackle one of the most difficult and misunderstood questions in the church today: whether the Bible has a coherent and consistent vision for sexuality and gender. Rather than singling out one issue, they examine God’s design for sex, the many ways humans depart from it, and why Scripture applies the same standard to everyone. This episode confronts charges of hypocrisy, challenges selective outrage, and asks a deeper question: not who fails, but who defines what faithfulness actually is.

In this opening episode, hosts Greg and Nathan begin with clarity in a confused cultural moment. They walk through Scripture to show how God’s design for sexuality and gender is rooted in creation, reaffirmed by Jesus, and aimed at human flourishing. This conversation isn’t about politics or singling out groups—it’s about what God has clearly said, why His boundaries are good, and how truth and compassion belong together. Before discussing complexity or pastoral care, Greg and Nathan lay the biblical foundation for understanding sex, gender, marriage, and identity in light of God’s good design.

In this episode, Greg and Nathan introduce their upcoming January series. Going live, Greg and Nathan will take on Sexuality, Gender, and the Bible in one of CFC's Core class. With a pastoral heart marked by clarity, honesty, humility, and compassion, Greg and Nathan will explain what they mean by “biblical sexual ethics,” why it matters for human flourishing, and why churches so often avoid or mishandle these conversations. They walk through the three-week arc—from God’s design, to the wide range of ways we all fall short, to how Christians can hold deep conviction while loving people well—and share the commitments shaping the whole series: Scripture, truth, grace, and care for real people with real wounds. The episode closes with an invitation to listen with curiosity rather than defensiveness, submit questions, and join a no-shame, no-yelling pursuit of truth and grace as the series begins next week.

Check out to see what Greg and Nathan have cooking for the 2026 Year.

In the fourth and final episode of Promised & Fulfilled, hosts Greg and Nathan turn to one of the most hope-filled promises in all of Scripture. In “A Light to the Nations: Isaiah’s Vision of Redemption,” they explore Isaiah 9 and the breathtaking declaration that a great light would shine on people walking in darkness.

Spoken into a time of judgment, fear, and uncertainty, Isaiah’s prophecy points forward to a coming King—one whose reign would bring peace without end. Greg and Nathan unpack how this promise finds its fulfillment in the birth of Jesus Christ, announced to the shepherds as “a Savior… who is Christ the Lord” (Luke 2:11) and revealed as the true light who overcomes the darkness (John 1:4–5).

This episode explores:

• The historical and spiritual darkness surrounding Isaiah’s prophecy

• The meaning behind the messianic titles: Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace

• How Jesus embodies the light, peace, and righteous rule foretold by Isaiah

• What it means to live today in the tension of the “already and not yet” of Christ’s kingdom

As the series concludes, this conversation invites listeners to rejoice that the light has already come—and to live with hope as we await the full and final fulfillment of His eternal reign.

“The people who walked in darkness have seen a great light.” (Isaiah 9:2, ESV)

In this third episode of Promised & Fulfilled: Christmas through the Eyes of Prophecy, hosts Greg and Nathan turn their attention to a small town with an enormous promise. “From Ancient Days: The Ruler from Bethlehem” explores Micah 5:2 and its stunning claim that Israel’s long-awaited ruler would come from humble Bethlehem—yet have origins stretching back to eternity.

Set against the looming threat of Assyrian invasion, Micah’s prophecy reignited hope by pointing to a future king in the line of David. Greg and Nathan unpack why Bethlehem mattered so deeply in Israel’s story, how first-century Jews understood this promise, and why Matthew highlights the prophecy when recounting the Magi’s visit and Herod’s fear.

This episode connects the geography of Jesus’ birth with the theology of His identity, showing how the One born in David’s city is also the eternal ruler “from ancient days.” Along the way, the conversation explores Jesus’ lineage, messianic expectations, and what Micah 5 reveals about Christ’s divine nature.

Join Greg and Nathan as they trace the promise from prophecy to fulfillment—and discover how the Christmas story declares that the eternal King entered history in the most unexpected place.

In this episode, Greg and Nathan continue in their series, Promised & Fulfilled, the hosts journey into one of the most iconic and debated prophecies in Scripture: Isaiah’s promise of a virgin-born son called Immanuel—“God with us.”

Greg and Nathan unpack the drama of Isaiah 7:14 against the backdrop of the Syro-Ephraimite crisis, where King Ahaz faced political panic and spiritual compromise. Into that moment, God offered a sign—a child whose birth would speak both judgment and hope. But how does this ancient promise connect to the quiet, miraculous arrival of Jesus in Bethlehem centuries later?

Drawing from Isaiah 7:14 and Matthew 1:22–23, the episode explores:

• The historical setting of Ahaz and the looming threats of Syria and Israel

• The meaning of the Hebrew ‘almah and the Septuagint’s use of parthenos (“virgin”)

• How Matthew reads Isaiah’s words as ultimately fulfilled in Christ

• The rich theme of typology and the possibility of dual fulfillment—one child in Ahaz’s day, another in the fullness of time

Thoughtful, accessible, and rooted in Scripture, this episode invites listeners to behold the wonder of Immanuel—God with us—promised in prophecy and fulfilled at Christmas.

Podcast Series: Promised & Fulfilled: Christmas Through the Eyes of Prophecy Episode 1: Echoes of Promise: Understanding Prophecy in the Old Testament

Step back into the world of ancient Israel as Greg and Nathan launch their four-part Christmas series, Promised & Fulfilled. In this opening episode, “Echoes of Promise,” the hosts explore how the earliest hints of Christmas were woven into the fabric of Israel’s story long before a manger ever held a child.

Greg and Nathan unpack what “prophecy” meant to the original hearers—ordinary Israelites who listened to God’s word through His appointed messengers. They discuss the prophet’s dual task of forth-telling (calling God’s people back to faithfulness) and foretelling (revealing what God would do in the future), laying the groundwork for understanding how Old Testament promises point both to immediate events and to the long-awaited Messiah.

Drawing from key passages like Deuteronomy 18:15, Isaiah 7:14, the Davidic Covenant in 2 Samuel 7:12–13, and Hosea 11:1, the hosts explore the concept of dual fulfillment—how one prophecy can hold both a near-term, historical meaning and a far-reaching, messianic one. They also shed light on why many in Jesus’ day expected a political liberator rather than a suffering Savior.

To deepen the conversation, Greg and Nathan tackle questions such as: • What did Old Testament believers really expect when they heard promises of a coming deliverer? • How did the idea of dual fulfillment develop in Jewish thought? • Why do some prophecies seem to stretch across centuries? • And what misconceptions do modern Christians often bring to biblical prophecy?

Whether you’re new to Old Testament prophecy or looking to see the Christmas story with fresh clarity, this episode invites you to hear the echoes of promise that shaped Israel’s hope—and still shape ours today.
