When discussing the evidences for Jesus’ resurrection, many often make mention of the empty tomb and the various appearances of the Lord Jesus, but very few if any make mention of the future church.  In John 20:29, after appearing to a skeptical Thomas, Jesus says there is going to be a future group of believers who are going to believe in Him without seeing.  He tells Thomas, 

“Have you believed because you have seen me? Blessed are those who have not seen and yet have believed.”

And this group of future believers give strong evidence for Jesus’ resurrection.  Scripture is clear that those who have been saved—those who have taken a stand for Christ and continue standing for Him—those who are in Christ and live as Christ give strong evidence for His resurrection.
