Yes, the Bible identifies the true followers of Christ. (Caveat: this is dependent on a person believing that the Bible is God's special "message" to mankind, penned by men, but dictated by God. Later we will discuss why this God evidently favors white Europeans over black and brown and yellow nations of mankind.)
MATT 7:15-20 ~ “Beware of false prophets, who come to you in sheep’s clothing, but inwardly they are ravenous wolves. 16 You will know them by their fruits. Do men gather grapes from thornbushes or figs from thistles? 17 Even so, every good tree bears good fruit, but a bad tree bears bad fruit. 18 A good tree cannot bear bad fruit, nor can a bad tree bear good fruit. 19 Every tree that does not bear good fruit is cut down and thrown into the fire. 20 Therefore by their fruits you will know them."
What fruits do we see being produced in the religion of Jehovah's Witnesses?
MILLION$ in judgements and settlements for shielding pedophile abusers, in many different nations. Is this "good fruitage"? While other religious groups and organizations are publicly apologizing for past policies that allowed similar situations, the Governing Body open declares that any accusations of child abuse are lies from Satan's cohorts to discredit JW's. (Judges and juries are not seeing it that way.) Is this "good fruitage"?
The policy of disfellowshipping and shunning (they say unrepentant--but who is to judge?) members, which includes shunning of parents, children, siblings, etc. They state that even a phone call or email is not allowed. (What if your DF child is in danger and you refuse that call?) Several countries around the world have concerns of the detrimental effect this has on the family network and thus on society. Is this "good fruitage"?
Their policy of refusing blood transfusions has cost many, many followers their very lives. This is no where found to be scriptural in any other orthodox religion. Even the most conservative Jews have accepted this interpretation from the Old Testament words (whereas they do hold to the other extreme rules of the Law). JW's did not interpret it this way until the 1940's or 1950's, and yet they claim that Jesus selected them as the One True Religion in 1914. (Jesus was evidently running a little late with the "news" about blood.)
Their changing policy on organ transplants. When organ transplantation was new on the scene, JW's condemned it and a JW would be DFd for having an organ transplant. It is cannibalism and against Bible principles. But, as the procedure became more common in medicine and more accepted and in treatment for organ failure, they changed their "understanding" on transplants. It is still "cannibalism" but, yes, this is in the WT -- there is nothing in the Bible "outlawing" cannibalism. How many persons died prematurely because they refused the transplant of a kidney or liver or heart? Is this "good fruitage"?
Decades ago, JW's condemned vaccinations in much the same way as they condemned transplants. Now vaccinations are acceptable medical procedure. How many children suffered illness or even death or disability due to this unscriptural doctrine? Is this "good fruitage"?
Are Jehovah's Witnesses producing the "good fruits" that Jesus said would identify his disciples?
