Matthew 28:1-10, Revelation 6 - When Jesus stepped out of that grave, death was officially defeated and every single person on the earth could know two things for sure:
1. They could have eternal life through belief in Jesus.
2. They had no excuse to not follow Jesus.
Right now, God would be justified to bring an end to the world and call everybody out on who they've trusted for their eternal life. Yet, here we are, and we each still have a chance to either get right with God or do more for God. Which are you. Let's serve Him with joy.
