In this episode, I sat down once again with Simeon Costa for a conversation that I believe is both timely and foundational. We focused on a subject that is often minimised or misunderstood – baptism.

What struck me throughout this conversation was how consistently Scripture presents baptism not as a symbol to be appreciated later, but as an obedient response to faith that happens now. As Simeon walked us through Acts, the Epistles, and the Old Testament, it became clear that baptism is woven into the story of redemption from Genesis to Revelation. It is not a human work, but a God-ordained response enabled by grace.

This episode isn’t about winning arguments or elevating tradition. It’s about letting the Bible speak plainly. When the apostles preached the gospel, baptism was never an optional add-on, it was commanded and connected to repentance, remission of sins, and new life in Christ.


10 Key Takeaways

  1. Baptism was never optional in the early church
    In the Book of Acts, belief and baptism are always connected. When people asked, “What do we do?” the answer was immediate: repent and be baptised.
  2. Baptism is not a work—it’s a response
    Scripture distinguishes between works of the law and obedience of faith. Baptism belongs in the second category.
  3. The apostles treated baptism with urgency
    From Acts 2 to Acts 22, baptism wasn’t delayed, scheduled, or softened—it was commanded.
  4. The Bible links baptism to the washing away of sins
    Acts 22:16 and Acts 2:38 explicitly connect baptism with remission and cleansing, not mere symbolism.
  5. Calling on the name of Jesus is consistently tied to baptism
    Throughout Acts, the name of Jesus is invoked at baptism as an appeal for salvation and authority.
  6. Old Testament patterns prepare us for baptism
    Noah and the flood, Israel through the Red Sea, circumcision, and the tabernacle all point toward cleansing, covenant, and new life.
  7. Baptism marks entrance into covenant
    Just as circumcision was the sign of the Old Covenant, baptism is the sign of the New.
  8. Romans 6 presents baptism as participation in Christ’s death and resurrection
    Being “buried with Him” is not just metaphorical language—it’s baptismal language.
  9. New life begins where obedience meets faith
    Scripture presents baptism as the transition point between bondage and freedom, not the finish line.
  10. This is about alignment, not superiority
    The goal isn’t theological snobbery—it’s obedience to what Jesus and the apostles clearly taught.

Final Thought

Baptism is not about earning salvation, it’s about responding to the command of Jesus. When Scripture is allowed to speak without filters, baptism emerges not as an afterthought, but as a moment of transformation, obedience, and new life. If the Bible is clear, the response should be simple: get washed in the water.

If this episode stirred questions or conviction, I encourage you to return to Scripture and let it shape your response. That’s always where clarity begins.
