    Reverence for God’s Name | Pr. Oswald Sichula

    Pastor Oswald Sichula preached from Exodus 20:7 on “Reverence for God’s Name,” focusing on the third commandment and teaching that the Decalogue does not produce salvation but shapes how redeemed people live before God. He explained that while the first commandment calls believers to worship God alone and the second calls them to pure worship, the third commandment presses deeper into how God’s people speak about Him, bear His name, and live under His redemption, asking whether our lives magnify or trivialise His glory. God’s name is holy and should never be treated casually. First, he explained what it means to take God’s name in vain, showing that the commandment prohibits empty, careless, and thoughtless speech about God. This includes reducing God’s name through sin, using His name while living a double life, swearing falsely by His name, and religious hypocrisy where people profess to belong to God while living like the world. Calling oneself a child of God means carrying the name of God, and therefore our lives should reflect His holiness. Second, he spoke about manipulative and forced devotion, warning against using God or His Word as a spiritual lucky charm or a tool for personal gain instead of worshipping Him rightly. Referencing Exodus 20:7, he emphasised that God will not hold guiltless those who misuse His name, which is why the Israelites treated His name with deep seriousness and reverence. God is not distant or passive but an active participant in our worship, conversations, and daily lives, and this exposes the true condition of the human heart. The sermon challenged believers to examine where they have become casual in their walk with God and reminded them that true reverence comes from looking away from ourselves and towards Christ, the One who perfectly kept every commandment. He concluded by encouraging believers to cultivate lives where their lips and lifestyles match, through the help of the Holy Spirit who produces genuine reverence for God, while also reminding non-believers that this commandment ultimately calls them to repent and believe in the Lord Jesus Christ.

    The Exclusive and Pure Worship of God

    Pastor Collins Sakalunda preached from Exodus 20:3–6 on “The Exclusive and Pure Worship of God,” teaching that the Ten Commandments show Christians how to live in a way that reflects the image and character of God. He explained that the commandments are divided into two categories, with the first four regulating humanity’s relationship with God and the remaining commandments regulating relationships with others, reflecting the greatest commandments of loving God fully and loving one’s neighbour as oneself. He emphasised that the law is a reflection of God’s character and introduced the term’s theme, The Decalogue. First, he spoke about the exclusive worship of God from verse 3, explaining that the first commandment defines who alone deserves worship and that God will not share His glory with false gods. This commandment is foundational because it identifies the one true object of worship, and God has the right to demand exclusive worship because He alone is Creator, Deliverer, and Saviour, as supported in 1 Corinthians 8:4. Christians are therefore called to reject every false god and worship the true God alone. Second, he spoke about the pure worship of God, explaining that it is not enough to worship the right God; we must also worship Him in the right way. The second commandment teaches that our approach to God matters and warns against false worship and idolatry. He explained the four parts of the commandment: the prohibition against carved images because God is jealous for His glory, the command not to bow down to idols, the warning for those who hate God, and the greater promise of mercy for those who obey Him. In conclusion, he warned that many people today still struggle with the same idols Israel faced, and that even churches can fall into idolatry through things people manipulate or elevate above God. He ended by reminding us that true worship requires us to change rather than trying to reshape God, and that genuine worship can only come through a personal relationship with Christ.

    The Cross – Jesus Gives His Life | Pr. Oswald Sichula

    In Jesus’ time, the Jews expected the Messiah to solve their problems and defeat their enemies with mighty power. Yet Jesus accomplished this through the power of the cross. Many of us have heard about the cross or seen people wear crucifixes, yet carry on with little thought. We know Jesus died on the cross, but do we understand the access it gives us to God the Father? Find out as Pr. Oswald Sichula explains the power of the cross and the access it gives us to the Father from Mark 15:33–41.

    The King Enters Jerusalem | Pr. Chipita Sibale

    Pastor Chipita Sibale preached from Mark 11:1–11 on “The King Enters Jerusalem,” teaching that Jesus is the humble King whose kingship is spiritual rather than political, calling us to submit sincerely to His lordship in true worship. The sermon emphasised that believers must be willing to submit to the Lordship of Jesus Christ, and the passage was explained in three parts. First was sovereign preparation (verses 1–6), shows that Jesus deliberately prepared His entry into Jerusalem through command and obedience, leaving nothing to chance; the triumphal entry was fully planned, reflecting how every stage of Christ’s life—from His birth to His incarnation—unfolded under God’s sovereign authority, reminding us that nothing on earth happens by accident and that when God calls, we are to surrender everything because all things belong to Him. Second was the public celebration (verses 7–10), where the crowd’s actions fulfilled the prophecy of Zechariah 9:9 and honoured Jesus as King, demonstrating outward royal recognition. Third was the quiet divine examination (verse 11), where Jesus entered the temple and silently observed, revealing that many who praised Him publicly did not truly love Him, while Bethany represented genuine devotion. The sermon challenges us to consider what the King sees when He looks at our hearts and lives, reminding us that He is not deceived by outward appearances or religious activity, and that true submission goes beyond public praise to sincere inward devotion.

    The King Over Storms | Pr. Kennedy Kawambale

    Pastor Kennedy Kawambale preached from Mark 8:27–30 on “The True Confession,” teaching that Jesus is the Christ, the Son of the Living God, and that true discipleship begins with confessing Him as Lord and committing to follow Him. The sermon centred on the importance of the question, “Who do you say Jesus is?”, explaining that Christianity does not stand on opinion but on confession, and that the most important question in the world is what we believe about Jesus Christ. First, he spoke about an objective question, showing that Jesus’ identity is not shaped by personal comfort or preference but by how God has revealed Him, emphasising the exclusivity of Christ’s deity and pointing to 1 Timothy 2:5–6, reminding us that a Jesus who bends to our desires becomes an idol rather than the true Christ. Second, he explained that this is a question that divides, because admiration for Jesus is not the same as salvation; neutrality is impossible, and one may respect or admire Christ yet still completely miss Him. Third, he described Peter’s confession as a confession with depth, reminding us that Jesus did not die as a helpless victim and that the Christian life is a continual deepening in love and understanding, like longing for the bridegroom. Finally, he revealed the state of the human heart, explaining that humanity desires the crown without the cross, as Peter initially did, and challenged us to examine whether our hearts have truly bowed to Christ. The call was to make a true confession and live a life of genuine discipleship, recognising that until we can confidently answer who Jesus is, we cannot fully understand what it means to follow Him.
