1 Do you now reject all of the wts teachings and doctrines?
I would prefer to say that I have come to my own conclusions by studying the Scriptures without the WTBTS blinders (their literature) on. After so doing, I share some teachings and doctrines with JWs as well as other sects of Christainity, and some that perhaps none of them hold.
2 What doctrines do you still believe in?
Those that can be clearly proven from Scripture without having to resort to supplemental material to support a clearly preconcieved doctrine.
For example, start with the Law of Love, then add to that those other things (all summed up in that law, but fully expounded on elsewhere) as follows:
Putting faith in God, his Son, Jesus Christ, his Son's ransom sacrifice's power to redeem us, and his inspired word the Holy Bible - Hebrews 10:12, 26; 11:6; 11:1-40; John 3:16-21; Romans chapters 4, 5 & 6; Romans 10: 9-17; Acts 4:12; 10:43; Matthew 26:28; Mark 3:28-30; James 4:17; 5:15; 1 John 4:9-14;Luke 13:23,24; 1 Timothy 4:10.
Practicing the fruitages of the Holy Spirit, doing our utmost to avoid sin -Galatians 5:19-25;1 Corinthians 6: 9,10; Matthew 12:31
Prayer - Matthew 5:44, 6:9, 26:41; 1 Thessalonians 5:17; James 5:16; Romans 12:21; Phillipians 4:6; Colossians 4:2; 1 Peter 4:7.
3 What doctrines have you stopped believing in?
All those that have no Scriptural support, and those that can be interpreted to have multiple, soundly Scripturally based, conclusions.
4 What doctrines are you not sure about?
If we're talking JW doctines, most. I believe only some of the doctrines taught by JWs (and organized Christian religions) have clear Scriptural support, in other words, there are, Scripturally, multiple ways to interpret the basis for many doctrines.
If one prays for Holy Sprit in faith, and studies the New Testament with the intent of examining each topic as to whether it is a law or rule that must be obeyed for salvation, versus a principle, suggestion, admonition, etc, versus chronology, prophesy, etc, one finds that the "core beliefs" are those necessary for each individuals salvation, while most of Scripture is for other purposes, and should be treated accordingly.
God judges the heart (cf. Hebrews 4:12), not whether one thinks the "right thoughts" in doctrinal matters of belief.
In the end, God will judge each of us as individuals, not as part of a "religion", "group", "organization", etc. Many hide behind the mask of their religion’s beliefs, letting them decide what is right and wrong, what is necessary for salvation, etc. It takes personal study, research, and the ensuing Love, Faith, and other Fruitages, along with the aforementioned Scriptural practices, to gain salvation.
That is why, imo, Jesus spoke these words in Matthew 7:13,14: "You can enter God's Kingdom only through the narrow gate. The highway to hell is broad, and its gate is wide for the many who choose the easy way. But the gateway to life is small, and the road is narrow, and only a few ever find it.
