When Adam and Eve disobeyed in the Garden, it didn't take God by surprise. Right then and there He promised a Saviour.
He told the serpent:
I will put enmity
Between you and the woman,
And between your seed and her Seed;
He shall bruise your head,
And you shall bruise his heel. Gen 3:15.
The seed of the woman, you will notice. Not the seed of the man. Jesus was to have no earthly father.
From the moment the promise was given, the powers of evil in this world did everything they knew to stop it being fulfilled. They sought to destroy the line from which the Saviour would come.
Cain was persuaded to kill Abel. There was an attempt to prevent Abraham from having a legitimate heir. Pharaoh ordered the death of all male Hebrew children. There were attempts to kill all the children in the royal line. Haman sought to kill all the Jews in the captivity. Herod killed all the young children in Bethlehem. There were attempts on Jesus' life in Nazareth, and on Galilee.
Finally, the Jewish religious leaders plotted His death. Judas agreed to give Him up. Pilate was persuaded to condemn Him.
It's not hard to imagine a colossal number of demons gathered around the cross. Did they say "We've got Him!" as the soldiers hammered the nails through His hands? Did they say "We've won!" as Jesus gave His last cry and yielded up His spirit?
If they did, they were going to be disappointed.
As we shall consider in the next several days, what appeared to be the greatest defeat in history was about to become history's greatest victory.
