Yes, Moses had faith (in God), and God was pleased with him, but -- nothing in the Hebrew scriptures indicates that prayers to God the Almighty were to be offered in the name of animal sacrifices. Or a messiah. Every prayer in the Hebrew scriptures (those in the Bible before the appearance of Christ) was directed to God, whose name is YHWH, Yahweh, or Jehovah in English depending on how you want to say it. suggest you read more about that in the Torah and the book of Hebrews. Besides, the Messiah (or God's SON) did not come down from heaven and sacrifice himself in Moses time. He was WITH God, his Father, in heaven until then. Then he went back to heaven after his resurrection.
1 John 4:12 - "No one has ever seen God; but if we love one another, God lives in us and his love is made complete in us."
Do you think John was kidding when he said that?
