which are the top several points that prove JWs wrong?
Welcome Teddnzo.
1. The top point is the denial of Justification for its members. I heard a millions times growing up that the New Covenant was only for 144K goverment position in God's Kindgom, and therefore, not for me.
But the bible says that the new covenant is "for the forgiveness of sins" MT. 26: 27-28
Romans 5: 1, 9 says that you cannot escape the wrath of God without being Justified.
You can never be good enough to avoid an adverse judgement because " all our righteousnesses are like filthy rags" (Is. 64: 6) And, "there is no one righteous, no not one".
2. The "All other organizations are false" WT doctrine. Looks like you still struggle with this one. There are lots of good individually goverened groups of Christians out there. Got is saving individuals.... not religions. That is the key point.
The reason we need a persoanl saviour, is because Hebrews 9:27 says there will be a personal judgment AFTER we die. We are not being judged now on how we respond to WT literature. That is absurd.
3. Gal. 1: 8,9 says that if we believe or preach anything other than what the apostles preached, we are "CURSED". This scripture alone destroys most of WT teachings because they admit that things like their two-tier salvation scheme wasn't taught by the apostles. The whole concept of "new light" is destroyed by Gal. 1:8,9
