How do we know Jesus is alive?

The evident change in a believer's life serves as a powerful testimony to the reality of Jesus' resurrection. When a person moves from death in sin to new life in Christ, it is the Holy Spirit's work that brings this transformation to fruition. This life change, which is marked by repentance and faith, illustrates the active presence of Christ within the believer, affirming not only His resurrection but also His continuing work in the hearts of those who believe. This is concisely highlighted in verses that speak of Christ living in us, which constitutes a compelling argument for His living presence today.
