How do we know that Christ is alive today?

The apostle Luke writes in Acts 1:3 that Jesus demonstrated many infallible proofs of His resurrection, showing Himself alive after His suffering to His disciples for forty days. This time of teaching about the kingdom of God solidified the reality of His resurrection. The resurrection is pivotal in Christian faith, affirming Jesus' victory over death and validating His divine nature as the Son of God. The continual work of the Holy Spirit in believers’ lives today is also a testimony to the living presence of Christ, who intercedes for us at the right hand of the Father.
