The resurrection is God's proof that there is a judgment day and that Jesus will be the one to judge everyone, according to the Apostle Paul in Acts 17:31. The resurrection also matters because through Jesus' death and resurrection, all who trust in him die to their old life of sin and are renewed inwardly by the power of the Holy Spirit to begin walking in holiness. We might not feel like the resurrection is important, but it is a fact that not only proves that we will have to stand before God one day, but it also shows us that new life can be found in Christ, simply by committing our lives to him, in repentance and faith.
