You're in a real muddle here, lymus. You're trying to make a distinction between 'lord / heir of all things' and 'God of all things' - and such a distinction does not exist in scripture!
Deut. 6:4 'Hear, O Israel: The LORD our God is one LORD:'
If Jesus Christ is not Lord, or God, then he is not worthy of worship. If he is Lord and God, then he is worthy of worship.
The mistake you are making is not recognising that God was in Jesus Christ reconciling the world unto himself.
Colossians 1:19,20. 'For it pleased the Father that in him [Jesus] should all fulness dwell; And having made peace through his cross, by him to reconcile all things unto himself; by him, I say, whether they be things in earth, or things in heaven.'
Hosea 13:4. 'Yet I am the LORD thy God from the land of Egypt, and thou shalt know no god but me: for there is no saviour beside me.'
Was Jesus Christ our saviour, or not? It amounts to the same question as the one about worship. Our saviour deserves our worship.
Sighs
1. David made distinction between Lord God his God and his lord the only begotten Son of God.
Mar 12:36 For David himself said by the Holy Ghost, The LORD said to my Lord, Sit thou on my right hand, till I make thine enemies thy footstool.
--------------------
2. Jesus made distinction between Lord God his Father and himself.
Joh 8:42 Jesus said unto them, If God were your Father, ye would love me: for I proceeded forth and came from God; neither came I of myself, but he sent me.
Joh 20:17 Jesus saith unto her, Touch me not; for I am not yet ascended to my Father: but go to my brethren, and say unto them, I ascend unto my Father, and your Father; and to my God, and your God.
------------------------
3. Luke made distinction between Lord God The Highest "Most High" and his only begotten Son.
Luk 1:32 He shall be great, and shall be called the Son of the Highest: and the Lord God shall give unto him the throne of his father David:
----------------------------
4. Corinthians distinguishes The God and Father who is the Head of Christ from Christ.
2Co 11:31 The God and Father of our Lord Jesus Christ, which is blessed for evermore, knoweth that I lie not.
1Co 11:3 But I would have you know, that the head of every man is Christ; and the head of the woman is the man; and the head of Christ is God.
-------------------------------
5. Timothy distinguishes Lord God from lord.
1Ti 1:2 Unto Timothy, my own son in the faith: Grace, mercy, and peace, from God our Father and Jesus Christ our Lord.
------------------------------------------
6. Romans distinguishes God from Jesus
Rom 1:8 First, I thank my God through Jesus Christ for you all, that your faith is spoken of throughout the whole world.
-------------------------
7. Isaiah distinguished Lord God from his righteous servant.
Isa 53:10 Yet it pleased the LORD to bruise him; he hath put him to grief: when thou shalt make his soul an offering for sin, he shall see his seed, he shall prolong his days, and the pleasure of the LORD shall prosper in his hand.
Isa 53:11 He shall see of the travail of his soul, and shall be satisfied: by his knowledge shall my righteous servant justify many; for he shall bear their iniquities.
----------------------------------------------
8. Jesus is not The Lord our God The Father who is The Mosh High God and Ancient of Days "Lord God"
Joh 4:23 But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him.
Heb 12:9 Furthermore we have had fathers of our flesh which corrected us, and we gave them reverence: shall we not much rather be in subjection unto the Father of spirits, and live?
Act 17:30 And the times of this ignorance God winked at; but now commandeth all men every where to repent:
Act 17:31 Because he hath appointed a day, in the which he will judge the world in righteousness by that man whom he hath ordained; whereof he hath given assurance unto all men, in that he hath raised him from the dead.
----------------------------------------------------
9. God our Father is the True Saviour because Jesus came in his name / authority. So on a Macro level God our Father is my Saviour with Jesus his righteous servant being his appointed Saviour.
Joh 5:43 I am come in my Father's name, and ye receive me not: if another shall come in his own name, him ye will receive.
Act 5:31 Him hath God exalted with his right hand to be a Prince and a Saviour, for to give repentance to Israel, and forgiveness of sins.
-----------------------------
10. God was in his Righteous Servant "Jesus" thru his Righteous Servant being subservient to his will and works; Thru his Righteous Servant declaring and representing him.
Joh 4:34 Jesus saith unto them, My meat is to do the will of him that sent me, and to finish his work.
Joh 10:37 If I do not the works of my Father, believe me not.
Joh 7:17 If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself.
Joh 1:18 No man hath seen God at any time; the only begotten Son, which is in the bosom of the Father, he hath declared him.
--------------------------
11. Deflect as you like, but according to the New Testament "Deu 6:4" is referring to The Father not his only begotten son.
Deu 6:4 Hear, O Israel: The LORD our God is one LORD:
Eph 4:6 One God and Father of all, who is above all, and through all, and in you all.
Joh 13:3 Jesus knowing that the Father had given all things into his hands, and that he was come from God, and went to God;
12. Commandments of God are of The Father because he is the only True God
Joh 12:49 For I have not spoken of myself; but the Father which sent me, he gave me a commandment, what I should say, and what I should speak.
Joh 12:50 And I know that his commandment is life everlasting: whatsoever I speak therefore, even as the Father said unto me, so I speak.
Joh 17:3 And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent.
