His resurrection is the judgment of acquittal for the whole world. Christ has become the firstfruits of them that slept. There were earthquakes when Jesus died and when He rose again. They occur constantly as signs of the coming judgment. Earthquakes remind us that only the Lord Jesus and His Word can help us.
Easter is a day of learning.
I learn about myself and I learn about Jesus. The Gospel teaches me to know Him and the power of His resurrection. That's why I came to church today. That's what happened on the first Easter Sunday. Ever since Christ rose from the dead on Sunday Christians meet on that day for worship.
