Peter says:
"Coming to Him as to a living stone, rejected indeed by men, but chosen by God and precious, you also, as living stones, are being built up a spiritual house, a holy priesthood, to offer up spiritual sacrifices acceptable to God through Jesus Christ."
Are our spiritual sacrifices also inspired? If not, you would need to prove that this specific example in Col. 3 means inspired (most uses of this term in scripture are not referring to the inspired word).
On the other hand, if the Spirit works in me, can I not say that my praises are spiritual as I can say my sacrifices are spiritual? After all, praise is a sacrifice (Heb. 13:15). Is man-made praise without a melody spiritual, but adding a melody makes it not spiritual?
This is a very odd, speculative and strange line of reasoning, in my opinion...
Brother, with all due respect, you are looking in the wrong place. See the context, "Let the word of Christ dwell in you richly..." Where does one find the Word of Christ? But the inspired Scriptures (2 Tim. 3:16). It says then "teaching and admonishing"? What ought we to be teaching? See Mt. 28:19-20 and 2 Tim. 3:16. What do we admonish with?
Well, I think we need to take the context, and what Paul says, what he means. And the context of Colossians, and the only other place in all of Scripture where these two words to teach and admonish are used together is in the book of Colossians. You'd think then that if used together they are most likely referring to similar things. So I ask you, what is Paul teaching and admonishing in Colossians 1:28 (the doctrinal section of Colossians)? And then I'll ask what are we to be teaching and admonishing in 3:16 (in the application section of Colossians)?
Col 1:12 Giving thanks unto the Father, which hath made us meet to be partakers of the inheritance of the saints in light:
Col 1:13 Who hath delivered us from the power of darkness, and hath translated us into the kingdom of his dear Son:
Col 1:14 In whom we have redemption through his blood, even the forgiveness of sins:
Col 1:15 Who is the image of the invisible God, the firstborn of every creature:
Col 1:16 For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him:
Col 1:17 And he is before all things, and by him all things consist.
Col 1:18 And he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all things he might have the preeminence.
Col 1:19 For it pleased the Father that in him should all fulness dwell;
Col 1:20 And, having made peace through the blood of his cross, by him to reconcile all things unto himself; by him, I say, whether they be things in earth, or things in heaven.
Col 1:21 And you, that were sometime alienated and enemies in your mind by wicked works, yet now hath he reconciled
Col 1:22 In the body of his flesh through death, to present you holy and unblameable and unreproveable in his sight:
Col 1:23 If ye continue in the faith grounded and settled, and be not moved away from the hope of the gospel, which ye have heard, and which was preached to every creature which is under heaven; whereof I Paul am made a minister;
Col 1:24 Who now rejoice in my sufferings for you, and fill up that which is behind of the afflictions of Christ in my flesh for his body's sake, which is the church:
Col 1:25 Whereof I am made a minister, according to the dispensation of God which is given to me for you, to fulfil the word of God;
Col 1:26 Even the mystery which hath been hid from ages and from generations, but now is made manifest to his saints:
Col 1:27 To whom God would make known what is the riches of the glory of this mystery among the Gentiles; which is Christ in you, the hope of glory:
Col 1:28 Whom we preach,
warning every man, and
teaching every man in all wisdom; that we may present every man perfect in Christ Jesus:
Col 1:29 Whereunto I also labour, striving according to his working, which worketh in me mightily.
('warning' is the same verb/participle form in Greek as what is found in 3:16 for "admonish")
3:16 "Let the
word of Christ dwell in you richly
in all wisdom;
teaching and
admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord."
The answer is the inspired word of God and the inspired word of God alone. And so it is that we are to teach and admonish one another the Word of God, and there it says in 3:16 "...in psalms, hymns, and spiritual songs..."
It's what we are to teach and admonish with, it is also (3:16) what is to dwell in us richly, and it is also (3:16) the source of all true wisdom.
