Sermon series: Isaiah 13-23: When God Speaks to the Nations

In Isaiah 22, Isaiah turns his attention from the surrounding nations to Jerusalem, where a crisis reveals where God’s people place their trust. In the midst of uncertainty and trouble, they are confronted with a question that remains relevant to us today: when crisis comes, where do we turn? As we consider Judah’s response to the crisis before them, we are reminded that even when our circumstances are beyond our control, there is a deeper question of where we place our trust and where our true security is found.

Sermon series: Isaiah 13-23: When God Speaks to the Nations

In these oracles about Babylon, Edom and Arabia, Isaiah 21 brings Judah into a world where nations rise and fall, questions are left unanswered and the future can change quickly. Yet, Isaiah does not give God’s people a complete map of what lies ahead. He brings them back repeatedly to what the LORD has said. Even when much remains uncertain, God’s Word remains sure.

Sermon series: Isaiah 12-23: When God Speaks to the Nations

Judah was tempted to turn to Egypt for help, the very nation that had once oppressed them. But God shows them where their hope truly lies. In His unsurpassed power, He strikes Egypt; in His unexpected grace, He heals them. And in so doing, He shows Judah, and us, that He alone is our unshakeable hope.

Sermon series: Isaiah 13-23: When God Speaks to the Nations

God teaches Judah not to be intimidated by Ephraim and Syria aligned against them, nor impressed by Cush seeking to align with them. Instead, they are to look to Him, the truly powerful One who is for them. Through Christ, we too can look to the One who is truly powerful and for us.

Sermon series: Isaiah 13-23: When God Speaks to the Nations

In this series of oracles directed against Philistia and Moab, Isaiah warns Judah not to look for refuge in nations who themselves need refuge. Philistia mistakes the changing of circumstances for security. Moab is brought low, yet remains too proud to receive the refuge that the LORD provides. In the midst of this, Isaiah points us to where true refuge is found: a King whose throne is established in steadfast love.

Sermon series: Isaiah 13-23: When God Speaks to the Nations

Isaiah 13-23 contains a series of oracles concerning the nations and the world around Judah. The first begins with Babylon, a kingdom that would become feared for its power and admired for its glory. Yet, Isaiah shows us the downfall of human pride through Babylon's fall, as well as God's compassion for His people and the reality of His unfailing purpose.

Sermon series: Topical Sermons

This passage shows us that the purpose of marriage is to ‘sanctify’ (v 26), which is to make us more and more like Jesus. The problem that works against this purpose is our sinful self-centredness (vs 28-29, 33). And the power for marriage is to be found in the love of our perfect Bridegroom, Jesus (vs 25, 29, 32). When we are satisfied in His love, we will make wise choices for marriage, work through hard things in marriage, and rejoice in the gift that is marriage.

Sermon series: 2-3 John: Walking in Love and Truth

This passage urges us, “do not imitate evil but imitate good,” because what we imitate reveals whether we are “from God” (v. 11). Diotrephes, “who likes to put himself first” (v. 9), is the evil to avoid. Demetrius, who “has received a good testimony” (v. 12), is the good to imitate. But we need more than examples, we need to be saved from our own desire to be first. Jesus is the preeminent One (Col. 1:18), yet laid down his life for us (John 15:13–15). When he is first, we don’t need to be, and we are freed to imitate good.

Sermon series: 2-3 John: Walking in Love and Truth

Truth is not merely something which we know and believe. It shapes how we love, live, and serve. This is what it means to walk in the truth. Gaius brought great joy to the apostle John because he was walking in the truth. His faith showed itself in practical, costly hospitality toward those serving for the sake of Jesus Christ. In a similar way, we reflect the love of Christ as welcome others into fellowship.

Sermon series: 2-3 John: Walking in Love and Truth

We are constantly being shaped by what we consume. But with so many voices claiming to speak for Christ, how do we avoid being deceived? John warns us to recognise the threat of deception, remain in the teaching of Christ, and rejoice together in Christian fellowship. There is no such thing as a “lone ranger” Christian; we need one another to stay close to Christ. And we stay close to Christ because He first came near to us. The deceivers went out, but Jesus came near—in the flesh, with truth and love—to live, die and rise again for us.
