Oh, that You would rend the heavens and come down, That the mountains might quake at Your presence—Isaiah 64:1
Isaiah prayed that God would come down to Earth and save Israel. God did even better than that, Jesus came down and not only saved the Jewish people, but he saved the entire world. This is exactly the expectations for the Messiah (Christ) God made in the flesh
When you understand what Jesus being the Messiah (Christ) means then you understand, that Jesus did say he was God.
For all of us have become like one who is unclean, And all our righteous deeds are like a filthy garment; And all of us wither like a leaf, And our iniquities, like the wind, take us away. Isaiah 64:6
The world had a sin problem and humanity could never provide its own salvation. We needed God to save us, we need a Savior, we needed Jesus Christ! Without the love, mercy , and grace from God through Christ, we would all perish! But thanks to our God coming down to Earth, to take our place, he saved us all
“She will bear a Son; and you shall call His name Jesus, for He will save His people from their sins.” Matthew 1:12
The Name Jesus (Yeshua) means salvation, God came down to Earth to give us salvation! Amen!
