In the Judeo-Christian tradition, today is the Sabbath, and tomorrow is the Lord's Day.  Yesterday, the sixth day of the week, God created man.  In our weakness,we turned from abundant life in The Garden of Eden. God, though he was not required to do so, initiated on the sixth day Paschal  ( the Greek word for "saving") actions, by granting, in the Garden of Gethsemane, Our Lord Jesus the courage to go through with The Father's plans.
        He died, so that we might live. Rather than accepting Abraham's sacrifice of Issac for the remission of humanity's sins and our potential not to trust in things unseen, God Almighty, in His goodness and in the fullness of time, sent flesh Incarnate, His Son, to be the only acceptable sacrifice and bridge back to Eternal Life. In our weekly memorials to God's saving work, Joseph of Arimathea, along with Mary Magdalene, and Mary the Mother of God had  already buried Jesus at  midday Saturday.
        Saturday, the Sabbath, is a period of waiting and of great hope. It is a day of Passover.  We remember that Jesus laid in the tomb from just before sundown Friday to the end of Saturday. Christians wait for that glorious day, Sunday, the day that God created the Earth, resurrected His Son from the dead, ascended to heaven ( in the United States at least)  and sent the Holy Spirit to remain with the human race. Our great hope is Sunday, the pinnacle day of the Christian Liturgical calender. Today we anticipate with great hope and love. Tomorrow we rejoice in the light and life to come.
        God Almighty, through Your Son's Life, Death, and Resurrection, may faithful everywhere recognize Your presence and grace with them from night to night and day to day. We ask this through Your Son, Our Lord Jesus Christ, who lives and reigns with You and the Holy Spirit for ever and ever. Amen.
