The point is not that you don't "have" to do anything. The point is that for the first time you will want to do something "God-pleasing" because we are told in the Bible that "anything not of faith is sin."
Further, Scripture tells us over and over that the only work that saves anyone is the work of Christ on the cross, which permits His righteousness to be imputed to the sinner.
Otherwise, you're just boasting, contrary to Paul's instructions in Eph. 2.
"Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost" -- Titus 3:6
Seems pretty clear to me.
WELL PUT,
imho.
Thx.
So, then how do you explain when Protestants want to do things that are not pleasing to God? "Partial salvation?" :)
