2. You don't follow the teachings of Jesus, only Paul so who are you to talk about another?
3. Many churches are corrupt, it's not the people but the doctrine brought in by false teachers.
4. Who are you to judge all Jehovah's witnesses, do you know all their hearts?
5. We shouldn't be interested in the military, those born of God should only be interested in pleasing God
6. There is only one gospel, and Paul preached it, and it's the same gospel that Jesus preached when he preached to the Jews and the gentiles.
7. The only way is Jesus, and he is the way the truth and the life!
8. Nor do I, not yet eternally anyway, I was saved through Christ from my past sins by the grace of God through faith, when I believed the word of God and repented, and God is saving me from this world and helping me to overcome every day through Christ by the power of the Holy Spirit. If I endure to the end, I have the hope of being eternally saved.
9. Maybe if you didn't speak to her in such a condescending and insulting manner then she may well answer you.
As for the rest of your post, I believe we should look at ourselves first, as there's enough wrong in our own hearts. The word of God does the judging.
