Just saw this move last week. It was an okay movie. When he said that Jesus was on a "rainbow" horse, I felt I needed to read the book. My DIL happened to have purchased it and I read it last night.
I have news for little boy Colton:
"And immediately I was in the spirit: and, behold, a throne was set in heaven, and one sat on the throne." Revelation 4:2
Page 95: Speaking of his sister that was stillborn. "It's okay Mommy," he said. "She's okay. God adopted her."
"Don't you mean Jesus adopted her?" she said.
"No Mommy. His Dad did."
What?
Page 100: "God is the biggest one there is. And he really, really loves us, Dad. You can't belieeeeve how much he loves us!"
"And do you know that Jesus sits right next to God?"
"Jesus' chair is right next to his Dad's!"
Page 101: "Well, pretend like you're in God's throne. Jesus sat right there," he said pointing to my right side.
Page 102: So, I'd had my glimpse into God's throne room, but Colton's descriptions had me wondering: if God the Father was seated on his throne with Jesus on his right and Gabriel on his left, where was Colton?
"They brought in a little chair for me," he said smiling. "I sat by God the Holy Spirit. Did you know that God is three persons, Dad?"
"I was sitting by God the Holy Spirit because I was praying for you. You needed the Holy Spirit, so I prayed for you."
So, I closed the book......
