Where does Rom. 6 teach that who we yield ourselves to is a matter of "freedom of will and choice"? You seem to be ASSUMING that, since it is nowhere to be found in the text
In fact, in Rom. 6 it says that "thanks be to GOD" that we have become slaves of righteousness. If it was a matter of merely our own "freedom of will and choice", we would have ourselves to thank, rather than God.
In its entirety, verse 17 mentions the doctrine that is obeyed (ie the Gospel). It is more than just a matter of becoming slaves to righteousness, and God is always to be thanked for making our choice possible. Thanking God for that does not negate that we chose whom to serve, we yielded ourselves to Him.
Btw, Rom. 6:16ff teaches that we are "slaves" ("douloi") of either sin or righteousness, not merely voluntary "servants" ("diakonoi"). Slaves don't have the "freedom" to "choose" who their master will be.
Slaves in general
might not choose their master, but this specific slave in these passages do in fact choose their master:
Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey
; whether of sin unto death, or of obedience unto righteousness?
And if it seem evil unto you to serve the Lord, choose you this day whom ye will serve
; whether the gods which your fathers served that were on the other side of the flood, or the gods of the Amorites, in whose land ye dwell: but as for me and my house, we will serve the Lord.
There is no getting around the fact that while we are always either a slave of sin or a slave of righteousness, there exists a moment in time outside
of the two that we go from one to another. That is biblically stated to be a choice, a matter of yielding yourself, and nothing has been presented that says that choice is bound. That is what makes it free.
As for Josh 24:15, it is irrelevant to the discussion, and doesn't teach "free will". If you would bother to actually READ your proof-text, it is directed at those who have ALREADY REJECTED God, and is a "choice" between two sets of FALSE gods:
Josh. 24:15 And if it is evil in your eyes to serve the LORD, choose this day whom you will serve, whether the gods your fathers served in the region beyond the River, or the gods of the Amorites in whose land you dwell. But as for me and my house, we will serve the LORD.”
I am sorry, but this is simply not true. I dont want to go into a long debate about it, but there are two grave errors in what you just said.
1) It is not "directed at those who ALREADY REJECTED God. If you take time to study the story up to this verse, Joshua has conquered the promised land with the people who were 19 and under when God said that their unbelieving elders and parents would never see it. So the ones who rejected God never made it to the promised land in the first place. Thats why Joshua continually refers to "your fathers
", he is talking about the people who were never allowed to be there. They were the ones serving other gods (josh 24:2)
2) He is not telling them to choose between "two sets of FALSE gods". You would again be well served to read the whole story.
14 Now therefore fear the Lord, and serve him in sincerity and in truth: and put away the gods which your fathers served on the other side of the flood, and in Egypt; and serve ye the Lord
15 And if it seem evil unto you to serve the Lord
, choose you this day whom ye will serve; whether the gods which your fathers served that were on the other side of the flood, or the gods of the Amorites, in whose land ye dwell: but as for me and my house, we will serve the Lord.
Their choices were to either A) serve the Lord, or B) if it seemed evil to serve the Lord, choose another god. At that point he gave two examples of other gods: the gods their fathers served which got them left out of the promised land, or the gods of the people whose land they just took. They said they would never serve other gods (verse 16), and proclaimed that they would serve the Lord (verse 21). Of course they ended up backsliding as usual, but at that moment, they had not rejected God, had been given a choice to serve Him or not, and chose to serve Him. They yielded themselves to Him and chose to be servants of righteousness, which is what Paul is speaking of in Romans 6.
