Thanks for this question it is a very good one and touches on one of the most profound subjects in the Bible, God Manifestation - how the Almighty God has chosen to reveal himself to His creation.
Jesus is the Greek form of the Hebrew name Joshua - Yahshua - "Yahweh is Salvation." Just as Joshua, having replaced Moses, led the children of Israel into the Promised Land so the latter day Joshua, Jesus of Nazareth, will lead his people into his Father's Kingdom having replaced the Law of Moses by the rule of Grace and the Gospel of the Kingdom and the forgiveness of sins.
Paul says in Philippians 2:9 that God has given him Jesus THE name that is above every name. That is, like the angel in Exodus 23:21, Jesus represents God to us. There will come a time when the Father's purpose will be fulfilled and we with our Lord will be one with the Father (1 John 3:1-3; John 17:20-23) and the Father will be "all in all." (1 Corinthians 15:28).
God bless and keep you in His way
