    Ministry According to Jesus (Mark 1:35-45)

    Sermon by Rev. David Ryu, on Sunday, April 19, 2026, at Diaspora Church. The sermon text comes from Mark 1:35-45. Every Christian is called to ministry—a life devoted to serving Christ, loving people, and advancing the gospel. But both our passion and practice of ministry, no matter how sincere and well-intended, must be carefully guided if we want to be useful in the service of Christ. In this passage, Mark shows us the true Servant sent of the Father. And by carefully studying His life, His Words, His heart, we learn vital lessons for faithful Christian ministry.

    Doubting Thomas Meets The Risen Christ (John 20:24-31)

    Sermon by Rev. David Ryu, on Easter Sunday, April 5, 2026, at Diaspora Church. The sermon text comes from John 20:24-31. Most people remember him as "Doubting Thomas". But John includes this unique account of a doubting disciple in his Gospel to persuade you to believe! Christianity is not a blind faith, in the sense that it requires you abandon all reason and logic. Thomas is not rejected and turned away for wanting to investigate the claim of the resurrection of Christ. In fact, we will see that his persistent and honest pursuit of truth is answered with grace.

    The True Meaning of the Cross (Galatians 3:13-14)

    Sermon by Rev. David Ryu, on Good Friday April 3, 2026, at Diaspora Church. The sermon text comes from Galatians 3:13-14. The cross is worn by many, but understood by few. Whether you hate the cross or love the cross, ignorance abounds. Do you have a true understanding of the cross of Jesus Christ? And if you do, does your heart still burn within you at the preaching of the cross? Because though it is foolishness to those who are perishing, it is the power of God and wisdom of God for salvation.

    The Lord Over Demons & Disease (Mark 1:21-34)

    Sermon by Rev. David Ryu, on Sunday March 22, 2026, at Diaspora Church. The sermon text comes from Mark 1:21-34. In this passage, the supreme authority of Christ is put on display. Jesus is the sovereign Lord over demons and disease, over the spiritual and physical. To the world that is perishing, there is only one hope, and one Savior—Jesus Christ, the Son of God, come in the flesh! Let us worship Him and serve Him.

    Called To Be Fishers of Men (Mark 1:16-20)

    Sermon by Pastor David Ryu, on Sunday March 15, 2026, at Diaspora Church. The sermon text comes from Mark 1:16-20. In this famous account of Jesus calling His first disciples, Mark directs our focus to the central matter: Jesus' call to discipleship and what that call demands. The first disciples were lowly fishermen and unimpressive in the eyes of the world. God chose foolish things of the world to put to shame the wise. He uses weak men and women to do great things! God calls us and makes us fishers of men, catching sinners living in darkness, and winning precious souls to Jesus Christ!

    Our Prophet, Priest, & King (Mark 1:9-15)

    Sermon by Pastor David Ryu, on Sunday March 1, 2026, at Diaspora Church. The sermon text comes from Mark 1:9-15. The purpose for which Christ has come was to redeem His people, but He executes that work of redemption as Prophet, Priest, and King. In the Baptism of Jesus, the Temptation of Jesus, and the Preaching of Jesus, we will clearly see that Jesus Christ is the ultimate Prophet, Priest and King, who has come for the salvation of His people.

    Jesus Christ, The Son of God (Mark 1:1-8)

    Sermon by Pastor David Ryu, on Sunday February 22, 2026, at Diaspora Church. The sermon text comes from Mark 1:1-8. We begin a new sermon series through the Gospel of Mark. Drawing upon reliable sources, and carried along by the Holy Spirit, Mark's record of the earthly life and ministry of Jesus is true and worthy of our full confidence. Jesus is the Christ, the Son of God, and the Lord God of Israel! Let us be glad and amazed, and let us prepare to receive the King of kings with hearts of repentance.

    True Christian Fellowship (1 Thessalonians 5:25-28)

    Sermon by Pastor David Ryu, on Sunday February 8, 2026, at Diaspora Church. The sermon text comes from 1 Thessalonians 5:25-28. Readers may be tempted to rush through these closing words of Paul's letter, assuming that nothing important remains to be said. But this final section contains valuable insights and applications for every believer. In these final four verses of 1 Thessalonians, what we see is Paul's vision for true Christian fellowship. We are, as it were, peering into Pastor Paul's heart for the shared life of the saints and deep communion in the church.
