Not hardly. At least not according to Scripture. Faithful believers will be richly rewarded for their faithfulness and obedience. KJV mentions "reward" 79 times, "rewarded" 13 times, and "rewards" 5 times.As believers we behave ourselves because we don't want to be "slaves" of the contrariness in our own flesh. And that's about the extent of it.
Also, 2 Cor 5:10 - For we must all appear before the judgment seat of Christ, so that each one may be recompensed for his deeds in the body, according to what he has done, whether good or bad.
Correct!We keep a 'lid' on it for our own temporal good, knowing that we can be enslaved even more, by not keeping a lid on it. And, then, we are faced with the challenge of not falling in hypocrisy, thinking we're better than some other sinner.
So, yeah, there are challenges aplenty. But none of this equates to "losing salvation."
Or Scripture would have plainly said so.
