The problem with the idea of us being "free" (especially if one ASSUMES libertarian "free will") is that it has an errant understanding of what the Scripture means by "free".
It's not that we're "free" TO do things...
It's that we are "free" FROM...
Rom. 6:16 Do you not know that if you present yourselves to anyone as obedient slaves, you are slaves of the one whom you obey, either of sin, which leads to death, or of obedience, which leads to righteousness?
We are never 100% "free".
We are either "slaves of sin".
Or we are "slaves of righteousness".
Rom. 6:17 But thanks be to God, that you who were once slaves of sin have become obedient from the heart to the standard of teaching to which you were committed,
Rom. 6:18 and, having been set free from sin, have become slaves of righteousness.
Reprobate: "slaves of sin", "free from righteousness";
Born again: "free from sin", "slaves of righteousness".
