Tomorrow is Palm Sunday. It's the day we remember Jesus' triumphal entry into Jerusalem before he would be crucified on a cross for our sins.
You can read the story for yourself in Matthew 21, Luke 19 and John 12.
"Hosanna in the highest!" the people shouted in Matthew 21:9. "Hosanna" is a Hebrew expression meaning "Save!" They knew they needed saving, but didn't yet understand what it is Jesus was going to save them from.
John the Baptist did. In John 1:29 he tells us exactly what Jesus came to do:
"Look, the Lamb of God, who takes away the sin of the world."
The Prophet Isaiah foretold of his coming in Isaiah 7:14 and 9:6:
"Therefore the Lord himself will give you a sign: The virgin will be with child and will give him the name Immanuel."
"For to us a child is born, to us a son is given, and the government will be on his shoulders. And he will be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace."
Immanuel means "God with us." Both verses from Isaiah make it abundantly clear that Jesus is God the Son come to earth.
And he came to die on a cross so that you and I could have life eternal!
Hosanna! Hosanna in the highest!
