Let me ask you this can someone saved stop believing? Or could it be they never really did and just not saved in the first place?
The Galatians were saved, yet they fell away from belief in Christ for justification back to keeping the Mosaic worship laws for justification.
I as a 26+ years believer even in my darkest, deepest sin filled vallies of my salvation can not emagion not believing in MY SALVATION, MESSIAH!!!
Yes,
'you' can not imagine no longer believing in Messiah. But there are believers with weaker faith who can imagine it, and who do fall away.
There are weak, immature believers who have faith, but the word is not deeply grounded in them and it can be easily uprooted from them. These are the 2nd type of soil believers in the Parable of the Sower. They believe for a while but since the word is not deeply rooted in them they fall away when trouble and persecution comes because of the word.
In a related teaching, Jesus talks about the severe punishment that will come to the stumbling block who causes a "
little one who believes in Me" to stumble and
go to the eternal, fiery hell:
6but whoever causes one of these little ones who believe in Me to stumble, it would be better for him to have a heavy millstone hung around his neck, and to be drowned in the depth of the sea.
8“If your hand or your foot causes you to stumble, cut it off and throw it from you; it is better for you to enter life crippled or lame, than to have two hands or two feet and be cast into the eternal fire. 9“If your eye causes you to stumble, pluck it out and throw it from you. It is better for you to enter life with one eye, than to have two eyes and be cast into the fiery hell.
He says it's better
for the sake of the little one's who believe in him that the person who causes the stumbling be cut off from the body (the church) because it's better for these
little ones who believe in him to do that
than for them to stumble and go to the eternal, fiery hell. But the church is sure that is not even a possibility because they are sure that once a person believes in Jesus and are saved they are always saved and can never go to the eternal hell.
