I herd a pastor touch on this topic today and he said that falling from grace is one person attempting, by their own righteousness to be justified - as in being self- righteous, instead of just accepting, what Jesus did for us on the cross. The things that we do that are bad (murder, adultry, swearing, lying, etc..) are just sins that we need to ask forgiveness for.
Just my two cents
There is a balance.
Little children, let no one deceive you. He who practices righteousness is righteous, just as He is righteous.
1 John 3:7
We are told to exercise godliness, practice righteousness, be led by the Spirit, abide in Him, walk in the spirit and you will not fulfill the lust's of the flesh...
The things speak to us of relationship with our God.
That we are to draw near to Him, and learn from Him, and seek Him, and ask Him for wisdom in these things.
He has not left us alone to live this life as orphans, for He loves us and desires us to walk with Him.
His mercy is new every morning.
We can do all things through Christ who strengthens us.
His life and righteousness within us will come pouring through us as we learn to yield to Him; to His Spirit within.
Sadly, folks have been taught to "explain away" the truths within the scriptures as nothing more than just a "fairytale story", written years later as some kind of
"spiritual fiction".
