[theophilus]

Jesus was not an ascended Master but a descended Master.

In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things were made through him, and without him was not any thing made that was made.
John 1:1-3 ESV

He was God and was never anything less than God. Along with the Father and the Holy Spirit he was the Creator of the world and all that is in it. When Adam sinned and brought death and sin into the world Jesus became a man so he could die as a sacrifice for our sins.

Have this mind among yourselves, which is yours in Christ Jesus, who, though he was in the form of God, did not count equality with God a thing to be grasped, but emptied himself, by taking the form of a servant, being born in the likeness of men.
Philippians 2:5-7 ESV

After his death God raised him from the dead and restored him to the position that had belonged to him eternally. Those who repent of their sins and put their faith in him will be raised to become part of God's family. He descended so he could raise us up.
