The resurrection of Jesus is the proof, the receipt that all sins and all diseases have been fully paid. Had Jesus not paid for absolutely all sins and absolutely all diseases, God would not have raised him from the dead.

His resurrection shows us two important things: We can be sure that his death is the full payment for all of mankind's sins and diseases.

“You were bought at a price.”

1 Corinthians 6:20

Furthermore: His resurrection is also the proof that he is God's Son:

“... declared to be the holy Son of God by the Spirit of holiness, according to the resurrection from the dead.”

Romans 1:4

God has given us visible proof that we can base our faith on. It is not a tale, but historical facts, which the Bible calls “proof” (Acts 1:3). We do not believe in fairy tales. Christianity is a historical revelation religion based on historical facts.
