As a non-Christian, one should realize their sin and their need for a Saviour. Jesus Christ is our way to forgiveness. If you want to know more the right side bar of my blog is clear about what someone needs to do to be forgiven.
His blood covers our sins when we ask his forgiveness...His Resurrection on Sunday fullfils the prophesy of a Saviour and finishes the work of salvation. All we have to do is accept it.
My belief, however, is more in line with a Wednesday crucifiction. This is because from Friday to Sunday is not 3 days... and the Last Supper was for the Passover. If you would like more information on this, I'd be happy to supply the verse references and events of the Holy Week that leads to a Wednesday crucifiction.
For as Jonas was three days and three nights
in the whale's belly; so shall the Son of man be
three days and three nights in the heart of the earth.
Have a Good Friday...looking forward to the celebration of the Resurrection!
