First, the fact is that is what the scripture clearly says, so those who reject it have to have to deal with God about it.
Second, if anyone is doing works in order to get saved, he does not have perfect love,(1Jn.5:15-18) but is operating from fear, which perfect love drives out.
1Cor.13 is discussing the role of love in performing works and that means that fear cannot be present.
The 'faith plus works' crowd want to ignore clear scripture and the fact that God is quite capable of dealing with those who are saved but reject their Christian walk, by discipline on earth, (Gal.6), even to the sin unto death (1Jn.5), and losses of reward in heaven (2Jn).
What upsets the 'faith plus works' group is that they cannot understand that this is God's plan, not theirs.
Yes, AMEN on all points! There will always be consequences for straying. Otherwise, sin doesn't matter. And none of us believe that sin doesn't matter, no matter what we are accused of. But salvation is different. That is His dominion, and His dominion alone, as the Bible tells us. How presumptive it is of some to think that they can cause to effect the closing of their own salvations. I guess many men just have to know that they are in control.
