The first two chapters of the Book of Hebrews tells us some great things that YHWH our God has done:
Heb 1:2 God has spoken by His Son.
Heb 1:2 God has appointed His Son the heir of all things.
Heb 1:4 God has given to His Son a much more excellent name than that of angels.
Heb 1:9 God is the God of His Son. God has anointed His Son with the oil of gladness. (Ps.45:7)
Heb 1:13 The Son of God sits at the right hand of God and waits for God to make his enemies his footstool. (Ps.110:1)
Further on in Hebrews chapter 2, we find:
Heb 2:4 God has born witness to the words spoken by His Son with signs and wonders, miracles and gifts of the Holy Spirit.
Heb 2:5 God did not put the world to come in subjection to angels.
Heb 2:8 Instead, God is putting all things, leaving out nothing, under subjection to His Son. (Ps.8:4-6). This is still ongoing, for now we do not yet see all things under him.
Heb.2:10 God, for whom and by whom all things are made, makes His Son the captain of salvation, perfect through sufferings in order to bring many sons to glory.
Heb 2:11 The Son of God is one with those whom he has sanctified. As such, he is not ashamed to call them his brethren. (Ps. 22:22)
Heb 2:13 The Son of God will put his trust in God (2 Sam.22:3, Is.8:17)
Heb 2:13b The Son of God calls his brethren "the children whom God has given me" (Is.8:18)
Heb 2:17 The Son is a merciful and faithful high priest in all things .pertaining to God.
From Hebrews chapters 1 and 2 alone, we can see that the Son is not God and that God is not the Son.
God has done great things indeed. Blessed be the name of YHWH our God.
