The Holy Spirit in the New Testament portrays Jesus Christ as God’s “Firstborn" Son (Hebrews 1:6, Psalm 89:27);

Also I will make Him the firstborn, the highest of the kings of the earth. Revelation 1:5, ‭‭Psalm‬ ‭89:27‬ ‬

‭And God has chosen us to serve our God and formed us into a kingdomof priests who reign on the earth.””‬
‭‭‭Revelation‬ ‭5:10‬ ‭‬

‭And You have made us a kingdom royal race to serve our God and priests to our God, and we shall reign as kings over the earth! (Exodus 19:6; Isaiah 61:6, Revelation‬ ‭5:10‬)‭‬

God said when He brought His Firstborn Son into the world: “Let all my angels bow down before him and kiss him in worship.” Hebrews ‭1:6‬

The term firstborn has two main meanings. The fact that this son is the first born of his father. The second meaning refers to the rights and authority of a person, because they are the firstborn.

Our LORD is the “firstborn” He is the One who has been appointed by God to be in authority over all things.(Colossians 1:13-18)

Jesus holds the “birthright” and is the heir of all the Father has, God appointed His Son, Heir of everything, for through Him God created all things and all time. Hebrews ‭1:2‬

God has given Christ all of creation as a gift, because all was created for Him and it all exist for His Purpose. Yes, The Father loves His Son so much that all things have been given into His hands. (Colossians 1:16; John 3:35).

Jesus, the only begotten Son of God, is the natural “heir” of the Father. “God said to him, ‘You are my Son; today I have become your Father’” (Hebrews 5:5; cf. Psalm 2:7).

Christ’s inheritance is the whole universe, all that is in existence: Hebrews 1:2 says that the Son has been “appointed heir of all things.”

Being a co-heir with Christ means that we, as God’s adopted children, will share in the inheritance of Jesus. What belongs to Jesus will also belong to us. Christ gives us His glory (John 17:22), His riches (2 Corinthians 8:9), and all things (Hebrews 1:2).

We are as welcome in God’s family as Jesus is; we are “accepted in the Beloved” (Ephesians 1:6, NKJV). All that belongs to Jesus Christ will belong to us, the co-heirs, as well.

And being His child, you are His heir also: a heir of God and fellow heir with Christ sharing His inheritance with Him; Romans ‭8:17‬

Meaning, believers have been given the privilege of sharing Christ’s inheritance.

Now you enjoy being God’s very own son or daughter! And because you’re His, you can access everything your Father has—for you are a heir of God through Jesus, the Messiah! Galatians ‭4:7‬

Jesus said: “Everything that the Father has is Mine. That is what I meant when I said that the Spirit will take the things that are Mine and will reveal it to you. John ‭16:15‬
