First Khawaja, "religion(s)" was/were made by man/men! "Believers" or followers of Christ should only teach "The Gospel of Christ" according to Galatians 1:6-9 who were called Apostles after being anointed by the Holy Spirit to teach!
Although II Peter 3:14 says "Wherefore, beloved, seeing that ye look for such things, be diligent that ye MAY BE FOUND "OF HIM" in peace, WITHOUT SPOT, and blameless." Did you hear "may be found OF HIM...?" HE (His Word) JUDGES - not we ourselves!
Scripture says that we are to "...judge RIGHTEOUS judgment..." (John 7:24)! What is RIGHTEOUS judgment but the Word of God? (Numbers 23:19-He doesn't LIE!) Scripture further tells us that we are to "...warn them that are unruly (sinning - with the Word of God), encourage the fainthearted, support the WEAK, be PATIENT toward all men." (I Thess 5:14) Therefore, it is our duty as a follower of Christ to "warn" them according to His Word!
I Samuel 16:7 says "...Look not on his countenance...for the LORD seeth not as man seeth; for man looketh on the outward appearance, but the LORD looketh on the heart." Thank GOD for JESUS that HE is not "mere-man!"
Man tends to "look at one's actions" (unlike GOD looking at the heart) and judge but who's to say that person has not been "chosen?" What would we have said of David? Adulterer! What would we have said of Abraham? Liar! What would we have said of Paul? Murderer! MOST "chosen" by GOD were the worst of men according to "mere man!"
Precisely why I continue to tell ALL, be very careful when judging for judging must be done ONLY according to what His Word says (Scripture)! Who knows what "level" of faith that individual has? Are we (ALL) not still "growing" or "changing from glory to glory?" (II Corinthians 3:18). If not "growing," (changing), must be "perfect" and don't need Christ! Who needs doctor if not sick or who needs Christ if already "perfect?"
GOD can make a "jackass" speak, if he has been "chosen" (Numbers 22:28) so be "very careful" when judging especially if one is not using The Word of God! Scripture says "Judge not" which means YOU don't judge but His Word does (Hebrews 4:12)!
