How do you know all non-JWs who oppose JW doctrine are christians?
I'm a bible believing christian who has accepted the Lord Jesus Christ for my salvation.
How do I know ?
Because Gods word (bible) tells me.
(Rom 10:17) So then FAITH cometh ...by hearing the word of God.
And who is called the "word of truth" and the "Word of God" in the bible ?
Answer: Jesus Christ (Eph 1:12-13 & Rev 19:13)
So that means by believing Jesus died for my sins on the cross and rose from the dead 3 days later for my salvation I am trusting him as the word of truth (1Cor 15:1-4 & Eph 2:8-9)
btw- The "word of God" written (2Tim 3:16 & Heb 4:12) and Jesus as the "Word of God" (John 1:1) are CONNECTED
You know full well its the writings of the watchtower magazines that you consider to be inspired truth and you only use the NWT (which is not the bible) as a reference book to confirm what the mags say.
How many hours or even years have you and other JWs wasted going door to door witnessing for your watchtower thinking this will earn your salvation with God ?
Everlasting life is a FREE GIFT not of works but of grace through Christ only (Rom 4:4-5, 11:6, 6:23, Eph 2:8-9 & Tit 3:5)
