What is the power of a Christian testimony? In this Testimony Sunday message from Calvary Cork, Mike Neglia teaches from Revelation 12:11 on remembering what God has done and repeating the story of His grace, followed by a testimony conversation with Siobhan. In Revelation 12:11, God’s people overcome “by the blood of the Lamb and by the word of their testimony.” But what exactly is a testimony, and why does it matter? In this Testimony Sunday message from Calvary Cork, Mike Neglia teaches on the power of remembering and repeating God’s grace. A Christian testimony is not an autobiography, and it is not a story about how impressive we are. It is a declaration of what Jesus has done. It is the story of how the saving work of Christ intersects with ordinary human lives. Beginning with Revelation 12:10-11, this message looks at the blood of the Lamb as the foundation of every Christian testimony. Satan is the accuser, but the gospel answers every accusation through the finished work of Jesus Christ. We do not overcome because our stories are dramatic, impressive, or perfectly polished. We overcome because Jesus has died, risen again, and applied His saving grace to our lives. The sermon then traces the biblical pattern of testimony through Scripture. In Joshua 4, the stones of remembrance point future generations back to God’s deliverance. In Mark 5, Jesus tells the delivered man to go home and tell his friends how much the Lord has done for him. In John 9, the man born blind gives a simple but powerful testimony: “One thing I do know, that though I was blind, now I see.” This connects beautifully with the language of Amazing Grace: “I once was lost, but now am found, was blind, but now I see.” This message also explores how remembering God’s past faithfulness strengthens believers in present battles. Before David faced Goliath, he remembered how the Lord had delivered him from the lion and the bear. The God who has been faithful is the God who will be faithful. The sermon concludes with practical help for formulating your own testimony around three simple questions: Before Jesus - what was I trusting in? Meeting Jesus - how did He save me? Following Jesus - how is He changing me now? After the message, Mike speaks with Siobhan about her testimony, walking through her life before Christ, how Jesus saved her, and how He continues to work in her life today. The conversation models how a testimony does not need to include every detail of someone’s life, but should clearly point to the grace and faithfulness of Jesus.

Can I clearly tell the story of what Jesus has done for me? Where are the “stones of remembrance” in my life? Who could be encouraged by hearing what God has done? Am I allowing the blood of the Lamb to answer the accusations of the enemy?
