I contend fruitfulness is not a litmus test for salvation.
AMEN..........of course I would cite creation which speaks and is used as an example by Jesus and the bible, but..............................
a. Seed of an apple lays on ground
b. Seed sprouts <----IMMEDIATELY is an apple tree but NO fruit
c. Sprout grows numerous YEARS as an apple TREE still NO fruit
d. ONCE it sprouted it is an apple tree, still and APPLE TREE finally after a few YEARS puts on from one to ten apples
e. Said apple tree may bear for many years in abundance or....
f. Said apple tree loses ALL blooms in year 5 due to late frost and bears NO fruit...STILL an APPLE TREE
g. Said APPLE tree bears crappy, dried up fruit year 7 due to a massive drought....STILL an APPLE TREE
h. Said APPLE tree has crop wiped OUT due to worms year 10...STILL an APPLE TREE
i. SAID APPLE TREE wanes and produces less and less as it ages and eventually dies...WAS ALWAYS an APPLE TREE
WHEN was the above tree NEVER an apple tree or LOST it's status as an APPLE TREE....NEVER
I seen a peach tree one time that was growing along a 2 lane highway in the ditch put on so much fruit that the limbs were almost to the breaking point....the same year that it died.....I picked numerous 5 gallon buckets of fruit off of that tree....the next year it was dead.....only produced that one year.....I drove by that tree for over 7 years and it never produced fruit until that year and only one year....yet it was ALWAYS a peach tree.....
