When Jesus ascended to heaven, He not only sends the Holy Spirit to continue sanctifying the world, but also leaves us His Holy body and blood. On one hand, they commemorate His suffering and His resurrection on the Cross. On the other hand, they nourish our spiritual lives. After we received the body of Christ, our lives are united with His. Hence, we are like what St. Paul said, “Today I live, it is no longer I who live, but Christ who lives in me.” Just as one day, when our body return to the earth and become its fertilizers, we will indirectly become body of the earth. Christ sanctifies and renews the earth through us, in order to complete the new heaven and new earth indicated in Revelation. Thus, it is seen that we are closely related to the world. Every single breath of ours can admire the wonderfulness of God’s creation, and share His wonderful life.
