The last supper at passover.
It's not really, last as the LOrd said, as often as you do this in remembrance of me, you have life within you.
He also said, I will never leave you or forsake you.
He honors us, and if we welcome him spiritually he comes in REv.
I don't know why God choose the blood as a covenant, but during Egypt's,
escape of the Hebrew slaves, the plagues were going through the land of Egypt
terrible things were happing all over, and to everyone, because of ONE Man
Pharaoh the leader who hardened his heart, and wouldn't let them to go free.
His own son died, Pharaohs, plagues and the angle of death was coming when
Joshua Moses were told to put the blood of a lamb on their door posts, and
the angel of death would pass over them.
Today and then Jesus Christ knew that he was going to Golgotha the place of the skull, and his blood was going to be shed, like a sacrificial lamb.
So it is today, when we accept Jesus, The Son of God, HE made a blood covenant with us, of LIFE, LIBERTY, AND LOVE.
