Remember Mary did not come to the Grave site until the first day of the week which is Sunday. (John 20:1) "The first day of the week cometh Mary Magdalene early, when it was yet dark, unto the sepulcher", And it was early in the morning and it was still dark. But Jesus had already risen. So even here Jesus was gone before Easter Sunday Morning.
The Lord’s days begin and end at evening (sunset). (Gen. 1:5) And God called the light Day, and the darkness he called Night. And the evening and the morning were the first. All biblical days began and ended at sunset.
Jesus went into His grave right before the end of the Passover or Wed. evening. The passing of the Passover brought in the Feast of the Unleavened Bread. So Jesus would Have been in the Grave Wednesday night, Thursday daytime and Thursday night, Friday daytime, Friday night, Saturday daytime and Jesus rose right before the sun went down on Saturday. Hence one has the 3 days and 3 nights which Jesus prophesied.
His death Wednesday night is consistent with the comment of the prophet Daniel, stating the Messiah would be cut off (killed) in the midst of the week. Daniel 9:26-27 26 And after threescore and two weeks shall Messiah be cut off, but not for himself: and the people of the prince that shall come shall destroy the city and the sanctuary; and the end thereof shall be with a flood, and unto the end of the war desolations are determined. 27 And he shall confirm the covenant with many for one week: and in the midst of the week (Wednesday is the middle of the week) he shall cause the sacrifice and the oblation to cease, (Remember, Jesus is the sacrificial Passover Lamb).
I find this part interesting. God is still in the business of working through people. And yet I tell you the truth and you believe me not. An atheist can see this clearly then people who say that believe in Christ. Out of Jesus own mouth he says he would be in the grave for three days and three nights as the prophet Jonas was three days and three nights in the whale's belly (Matthew 12:38-40). Even when Jesus rose it was not Sunday Morning according to the verses in (St. John 20:1-4). There are many things that are being done contrary to the word of God, people must know this. I post a three or four page lesson and most people don't go back to the beginning and read it all. They just skim through the thread.
