It would seem that for our disposition to change, our circumstances need to change. But Jesus offers us a joy that is superior. It is not a product of circumstance; it's a product of Easter. Easter proves that God can take what normally causes people to weep and turn it into what causes people to rejoice.
Three days after Jesus’ death he rose victorious from the dead. The rest of eternity is now a victory march for the risen Christ. We are not just observers of Christ’s victory. We are more than fans cheering for our favorite athlete. Rather, we are active participants in Christ’s tirumph. The victory is ours, now and forever.
