Sermon by Pastor David Ryu, on Sunday December 21, 2025, at Diaspora Church. The sermon text comes from 1 Timothy 1:12-16.

You will never truly know a Merry Christmas unless you are gripped by the sinfulness of your sins, and even more so, gripped by the One who came to redeem the most vile of sinners. The Apostle Paul tells us that Christ Jesus came into the world to save sinners—including himself, the worst of sinners. In Paul's conversion and redemption, we see an example of God's amazing grace. Be thoroughly convinced of this: Christ is the great Savior for great sinners. We are unworthy. But Christ is worthy, and sufficient for us.

Sermon by Pastor David Ryu, on Sunday December 7, 2025, at Diaspora Church. The sermon text comes from 1 Thessalonians 5:16-18.

The pursuit of happiness is the pursuit of every human soul. But we are discontent, we are empty, we are bored, because we were made for greatness, which this fallen world cannot provide. The Word of God teaches that believers are called and saved unto a life of abounding joy, and now believers must live it out. To "rejoice always" is a biblical command. Pastor David Ryu explains how every Christian has a moral obligation to be happy. He points out how the modern church often separates joy from happiness. However, why would anyone want to follow Jesus if He cannot supply true happiness?
