Some among the many verses speaking of performance being an indicator rather than the cause of a person's salvation. Salvation by Works Christians typically confuse the condition for salvation with the condition of the saved: Jer 32:38-41
Jeremiah 32:38-42 says,
38 "And they shall be my people, and I will be their God:
39 And I will give them one heart, and one way, that they may fear me for ever, for the good of them, and of their children after them:
40 And I will make an everlasting covenant with them, that I will not turn away from them, to do them good; but I will put my fear in their hearts, that they shall not depart from me.
41 Yea, I will rejoice over them to do them good, and I will plant them in this land assuredly with my whole heart and with my whole soul." (Jeremiah 32:38-41).
This suggests that you believe in a form of reversed Calvinism. That God forces somehow His people to fear Him, and to do good (after they made a one time decision of believing in the Lord for salvation).
But this should be read in light of the whole counsel of God's Word. If not, you are simply focusing a laser beam on a particular text out of the Bible out of it's context, my friend. Lets do a quick summary of the verses:
In Verse 38, God says, "They shall be my people, and I will be their God."
Verse 39 says that God will give them one heart, one way, and they shall fear me forever.
Verse 40 says God will make an everlasting covenant with them, that I will not turn away from them, and I will put my fear in them, and they shall not depart from me.
Verse 41 says that God rejoices over them to do good, and God plants them in the land with His whole heart, and whole soul.
Verse 39 and Verse 40 mention the fear of the Lord.
This doesn't sound like OSAS to me because you do not have to fear in OSAS.
There is no reason to fear God because you are once saved, always saved.
No sin can separate you from God. You got your guaranteed ticket.
Anyways, it does sound like God is kind of enforcing Himself upon the believer a bit in Jeremiah 32:38-41. It can be read that way. But this would be taking the Bible out of it's context as a whole (if you were to do that).
The Bible also says:
"If my people, which are called by my name, shall humble themselves, and pray, and seek my face, and turn from their wicked ways; then will I hear from heaven, and will forgive their sin, and will heal their land."
(2 Chronicles 7:14).
So it is a cooperation. God does not really force Himself to make His people to be a certain way. They have to cooperate with God in doing good. They are not mind altered against their will to do good. In fact, you yourself admit that the believer will always sin occasionally, so they really are not fearing the Lord and prevented from departing from God as verse 40 says.
Also, if we were to look at the reverse chapter number of Jeremiah 32 (i.e. Jeremiah 23), we learn about those Pastors who justify sin are in a heap of trouble with God.
Jeremiah 23:1-4:
1 "Woe be unto the pastors that destroy and scatter the sheep of my pasture! saith the Lord.
2 Therefore thus saith the Lord God of Israel against the pastors that feed my people; Ye have scattered my flock, and driven them away, and have not visited them: behold, I will visit upon you the evil of your doings, saith the Lord.
3 And I will gather the remnant of my flock out of all countries whither I have driven them, and will bring them again to their folds; and they shall be fruitful and increase.
4 And I will set up shepherds over them which shall feed them: and they shall fear no more, nor be dismayed, neither shall they be lacking, saith the Lord."
Jeremiah 23:9-15:
9 "Mine heart within me is broken because of the prophets; all my bones shake; I am like a drunken man, and like a man whom wine hath overcome, because of the LORD, and because of the words of his holiness.
10 For the land is full of adulterers; for because of swearing the land mourneth; the pleasant places of the wilderness are dried up, and their course is evil, and their force is not right.
11 For both prophet and priest are profane; yea, in my house have I found their wickedness, saith the LORD.
12 Wherefore their way shall be unto them as slippery ways in the darkness: they shall be driven on, and fall therein: for I will bring evil upon them, even the year of their visitation, saith the LORD.
13 And I have seen folly in the prophets of Samaria; they prophesied in Baal, and caused my people Israel to err.
14 I have seen also in the prophets of Jerusalem an horrible thing: they commit adultery, and walk in lies: they strengthen also the hands of evildoers, that none doth return from his wickedness: they are all of them unto me as Sodom, and the inhabitants thereof as Gomorrah.
15 Therefore thus saith the LORD of hosts concerning the prophets; Behold, I will feed them with wormwood, and make them drink the water of gall: for from the prophets of Jerusalem is profaneness gone forth into all the land."
I see these above passages in Jeremiah 23 as referring to a Pastor or teacher justifying even a little bit of sin. For why wouldn't this be the case? Adam and Eve fell away due to just their breaking of only one command by God. The devil tricked Eve into buying into the lie that she could break God's law and not die. This same lie is being pushed today in Christendom.
In any event, may God's goodness be upon you (even if we may disagree strongly on what the Bible says).
