How do we know the resurrection of Jesus is a sign for good?

The resurrection of Jesus Christ is described as the definitive token for good. It fulfills biblical prophecy and is confirmed through the apostles’ testimonies in the New Testament. In the context of Psalm 86, David's plea for a sign is fulfilled in Christ, whose resurrection signifies His victory over sin and the fulfillment of God's covenant promises. As noted, only the eyes of faith can truly see and appreciate this incredible sign. The resurrection assures believers of their own future resurrection and the reality of redemption.
