After His crucifixion, Jesus rose from the dead on the third day.
What should the resurrection mean to you? If you’re a believer, you should be happy. The One you love is alive! He’s free from death! He has the power of life, and He’s shown you by giving you life. He’s satisfied the debt of your sin, you will pass safely through the Judgment. Rejoice then, and praise Him for all His goodness to you!
But what about you who haven’t trusted Him? You should be afraid. The fact that Jesus was raised means there will be a final judgment - He will be your judge. You will be raised and judged on that final day for all your sins unless you repent and turn to the Savior. So why wait any longer?
