Description

In this episode, we define one of the most central doctrines of the Christian faith: that God is one being who exists eternally as three distinct persons—Father, Son, and Holy Spirit. We examine what the Bible teaches, respond to common objections, and explain why the Trinity is essential to understanding the Gospel.

Episode 16: Are Jehovah's Witnesses Christian?

Are Jehovah's Witnesses Christian? At first glance, many people assume the answer is yes. Jehovah's Witnesses believe in Jesus, use the Bible, and actively share their faith. So why have Christians historically reached a different conclusion? In this episode, we examine what Jehovah's Witnesses believe about Jesus, the Trinity, the resurrection, and the Holy Spirit, and compare those teachings to the doctrines of historic Christianity. We'll discuss why the identity of Jesus is at the center of this debate, why the bodily resurrection matters, and why Christians throughout history have viewed Jehovah's Witness theology as fundamentally different from biblical Christianity. As always, our goal is not to attack people, but to examine truth claims in light of Scripture.

Episode 15: Are Mormons Christian?

Are Mormons Christian? Members of The Church of Jesus Christ of Latter-day Saints use the Bible, talk about Jesus, and often live moral, family-oriented lives. So why have Christians historically concluded that Mormonism is not a denomination within Christianity, but a separate religious system? In this episode, we compare the teachings of Mormonism with the teachings of Scripture and historic Christianity. We examine the nature of God, the identity of Jesus Christ, the Trinity, continuing revelation, salvation, exaltation, and the claim that Christianity fell into complete apostasy before being restored through Joseph Smith. This episode is not an attack on individual Mormons. Rather, it is an examination of truth claims and a comparison of doctrine with Scripture.

It's trusting where the evidence leads.

Episode 14: What Is a Christian?

What actually makes someone a Christian? Is it church attendance? Believing in God? Being a good person? Baptism? Family tradition? In this episode of Practical Apologetics, we answer one of the most foundational questions in Christianity: What is a Christian? Many people claim the Christian label, and many groups use Christian language, quote the Bible, and talk about Jesus. But what does Scripture actually say defines biblical Christianity? We’ll discuss: • What a Christian is not • Why Christianity is centered on Jesus Christ • Why there is only one biblical Jesus • The essential beliefs that define Christianity • Why redefining the gospel changes Christianity itself Whether you’re a Christian wanting clarity or a skeptic trying to understand what Christians actually believe, this episode is designed to define Christianity fairly and biblically.

Episode 13: Why Did Jesus Have to Die?

Why did Jesus have to die? If God is loving, why was the cross necessary? Why sacrifice? Why blood? And why couldn’t God just forgive people? In this episode of Practical Apologetics, we explore one of the most important questions in Christianity by tracing the story from Genesis to the cross. We discuss sin, sacrifice, the Old Testament covenant system, Passover, the spotless lamb, and how Jesus fulfilled what the sacrificial system had been pointing toward all along. Was the cross an accident? Or was it the plan from the beginning?

Episode 12: What Is the Gospel?

What is the gospel? It’s a word that gets used often, but rarely defined clearly. Is it a lifestyle? A set of teachings? Or something more? In this episode, we break down the gospel in simple, biblical terms. The gospel is not advice about what you should do. It is the good news of what God has already done through Jesus Christ. We walk through: * The true meaning of the word “gospel” * The core message found in 1 Corinthians 15:3–4 * Why the gospel is necessary * How the gospel saves * And how you can respond to it today This episode also includes a direct invitation to respond to the gospel and a simple explanation of repentance and faith.
