How the Cape Town Church in South Africa shares the Good News through Mustard Seed Missions
Vida Li Sik • May 20, 2019
The Cape Town Church of Christ, in South Africa, has a number of talented people in their midst. One of them, Sarien Van Rooyen, is the artistic brilliance behind all the material created for the website, www.mustardseedmissions.co.za, a special site created to disseminate all the material created for the sermons and sermon series presented at the church.

Sarien became a disciple five years ago and is a graphic designer by profession. "God has blessed me to be creative and to use my talent for Him. I used to go onto the church's website and made suggestions on things we could improve. I then started working as a volunteer for Mustard Seed Missions, which was created in 2013, and recently became a full-time worker on the site," she shares.
What makes this site so special is that not only is all the material free (sponsored through contributions by the members of the church), but everything that has been created for a sermon is also available. This includes the video and audio files of the sermon as well as all the supporting material, including the logo, sermon images and sermon notes.
This allows anyone, especially hard-pressed-for-time leaders of smaller churches, who don't have the luxury of a full-time payed position, to access these high quality professional materials and use them as either a video sermon or integrating the materials into their own presentation.
A secondary function is to provide access to the leadership workshop videos and training materials that have been used during these sessions.
Mustard Seed Missions has been created to:
Resource
- To provide a high-quality sermon series on video for either personal use or to be shown at a church service as part of the service.
Equip
- To provide video training material to Family Group leaders through video messages, articles, booklets or recommended books.
Inspire
- To lift our faith through the power of God's Word, "until we all reach unity in the faith and in the knowledge of the Son of God and become mature, attaining to the whole measure of the fullness of Christ" (Ephesians 4v13 - NIV 2011).
Recently, Sarien started creating animated videos to illustrate Bible verses that can be used during a sermon. "We want people to feel like they're sitting next to the person talking," she explains.
The Good News is free and worth sharing with the world. Sarien says the vision for the site is to make new videos for everyday disciples to find relevant food for their souls.

The physics of the pendulum Picture an old grandfather clock in a quiet hallway. Its long brass pendulum swings steadily: tick, tock, tick, tock. Now give that pendulum a hard shove to the right. It does not simply glide back to the center and stop. It races right past the middle and sways just as far to the left. Left to its own momentum, a pendulum never rests at either extreme; it finds peace only when it hangs still at the center, held by gravity and its fixed point. The church behaves in much the same way. Push her too far toward one side of a truth and she does not gently settle into balance, she swings. Often for a whole generation toward the opposite error, and then back again, wounding people at both ends of the arc. And here is the crucial thing the clock teaches us: the pendulum comes to rest not by being frozen in place, but by being held. Balance is not the absence of force; it is the fixed point that keeps opposing pulls in tension so that the weight can finally hang still.

In the messy arena of human relationships, whether in marriage, the workplace, church family, or the volatile world of online discourse, we constantly feel the pull of opposing forces. One voice urges us to defend truth fiercely; another calls us to extend grace generously. This is the divine tension of disagreement: holding both conviction and compassion without letting go of either. Today, we turn to a passage that cuts to the heart of how we handle differences: “My dear brothers and sisters, take note of this: Everyone should be quick to listen, slow to speak and slow to become angry, because human anger does not produce the righteousness that God desires.” – James 1:19-20 (NIV) James, writing to scattered believers across the nations, doesn’t offer fluffy advice. He gives a practical, counter-cultural blueprint for godly relationships: Be quick to listen. Slow to speak. Slow to anger. These aren’t suggestions for better conversations; they are directives for producing the righteousness God desires. This passage applies to husbands and wives, children and parents, bosses and workers; everyone from the pulpit to the pew. We all need to train ourselves to be better listeners. The divine tension in James’ command Here lies the tension: Listening requires humility and self-control, while speaking (especially in defense of truth) feels urgent. Anger can arise when we perceive injustice or error, yet James holds these in balance. We must lean into listening first, restrain our tongues, and guard our hearts against hasty wrath. Why? Because “human anger does not produce the righteousness that God desires.” This isn’t a ban on all anger; Jesus displayed righteous anger in the temple (John 2:13-17). But human anger, tainted by our flesh, tends toward self-justification, escalation, and sin. It rarely births the fruit of the Spirit. The tension calls us to slow down enough for the Holy Spirit to lead, rather than our adrenaline. What science reveals about anger and “hearing” Modern neuroscience echoes what James knew by inspiration. When anger flares, our brain undergoes an “amygdala hijack.” The amygdala, the brain’s alarm system tied to fight-or-flight, floods the body with adrenaline and cortisol. This redirects resources: our heart rate spikes and oxygen flows to muscles for action, but our higher reasoning centers in the prefrontal cortex – responsible for judgment, empathy, and nuanced thinking – get suppressed. In this state, our ability to truly “hear” another person diminishes dramatically. Active listening, the tool that clarifies, disarms, and seeks understanding, becomes nearly impossible. We filter everything through threat detection, empathy drops, and we stop processing the other’s words for their actual meaning. Instead, while they are still speaking we start crafting rebuttals or counterattacks. This explains why conflicts escalate so quickly: we literally cannot hear well when flooded with anger. James’ call to be slow to anger is not just spiritual wisdom; it aligns with how God designed our brains to function best when governed by self-control rather than unchecked emotion. Recognizing our physiological limits isn’t about suppressing feelings, it’s about guarding our capacity for reason so we don’t accidentally sabotage the very justice we seek to defend. Even if the other person is operating out of a completely hijacked, high-emotion state, our calling to maintain self-control and clear thinking remains. When our prefrontal cortex goes offline, our hijacked brain defaults to intellectual shortcuts. This emotional flooding is precisely what predisposes us toward constructing caricatures, like the straw man, rather than engaging with the actual person.
