Why did the Lord die on the cross on a Friday?  The gospels tell us that he died on the preparation of the Passover,  the day during the Passover feast that the people prepared to keep the Sabbath-  so they could rest and worship on Saturday,  the seventh day of the week.
     Each of the main feasts God had given the people had a preparation day-  because each lasted at least a week.  So each time there was a major feast,  there was a Friday when God's people prepared for the Sabbath.  The Lord prepared us to rest in him and worship when he died on the cross for our sins.
     Each week of the year there was the first feast,  listed along with the main feasts,  and that feast was the Sabbath day of worship and rest.  So each year there were at least 52 preparation days.  Each week there was a reminder of the love of God in Christ.
     The cross fulfilled the redemption lamb of the Passover,  the sin offering of the Day of Atonement,  and every other offering of the Law of Moses.  The blood of Christ shed for us at Calvary prepares us to worship God every day.  Each day can be a day holy to the Lord.
     The church usually worships on Sunday,  the day that Christ rose from the dead-  but for the child of God there is no required day of worship.  We can enter boldly into the Most Holy Place in heaven through the blood of Christ.  We can walk in the light as he is in the light each day,  and our sins are taken away because he loved us and died for us.
     Christ died on a very ordinary day.  A Friday.  But it was a special day because it was the day God's people prepared to worship him each week.  He did everything necessary to prepare us to worship.  He gave us all of the best reasons to draw near to God.  No day is ordinary any more when it is the day he loved us,  and freed us from our sins with his own blood.
     Friday is also the day of the creation of Adam and Eve.  How generous of God to become flesh and become our Atonement on the very day he first gave us life.  By his Holy Spirit he offered himself once for our sins,  and gave us life and that more abundantly by becoming sin for us on the 6th day of the week.
     About 6,000 years have passed since the creation of the heavens and earth.  Still future is the Lord's return for his church and the 70th week of Daniel's prophecy.  
     Then following the times of judgement,  there is the Lord's return to earth and a wonderful period of rest for the earth-  a 7th millennium-  a Sabbath when the Lord returns to reign as King.  'For a day with the Lord is as a thousand years...'
     Beyond this time we read of the New Heavens and New Earth.  How lovely is the New Jerusalem,  the Paradise of God!  The 8th day of the Feast of Tabernacles is a picture this eternity.
     It was on the last day,  the great day of the feast,  that the Lord stood up and invited all who were thirsty to drink of Living Water.  He was freely offering them the presence of the Holy Spirit to fill and overflow their hearts.
     In the Jerusalem From Above the Water of Life flows from God's throne.  The glory of God gives light to the city,  and the Lamb is the Light thereof.  The Holy City from Heaven is the place of the great day of the feast.  
     The Paradise of God is pictured as an 8th day,  a time of new beginning.  How wonderful a blessing eternity is for all who believe in the Lord Jesus,  for all who simply trust in him there is grace.  Grace upon grace,  life and that more abundantly. 
     Christ died on the cross to show the love of God to us.  'In this was the love of God manifested towards us,  in that while we were yet sinners Christ died for us.'  'He that knew no sin became sin for us,  that we might become the righteousness of God in him.'
     'Just as Moses lifted up the serpent in the wilderness,  so also must the Son of Man be lifted up,'  the Lord said.  'That whosoever believes in him should not perish,  but have everlasting life.'
     'For God so loved the world that he gave his only begotten Son,  that whosoever believes in him should not perish,  but have everlasting life.'
     Christ died for whoever will draw near to God through him.  He came to offer grace to all-  and that is why the Bible ends the way it does: 

'The grace of our Lord Jesus Christ be with you all.  Amen.'
