When looking back on twi, we now see how much of it was operating as a cult as well as how much we followed their practices and doctrines believing we were doing God's will. As for now, scriptures say the following holds true.
God is not unrighteous to forget our work and labour of love which we showed in his name when we ministered to the believers and brought unbelievers to Christ. These treasures (rewards) are stored in heaven for us where they cannot be corrupted or stolen.
What things we did lose or were kept from having because of twi's hardheartedness, greed, lust, idolatry, etc. (Gal 5 has the full list), God is willing to heal, restore and give to us when we put our trust in him.
God has forgiven us for the sin in our lives during that time once we acknowledged them to him.
I'm sure others could add to this list or contest to it. The point is there is comfort in knowing that not all of our time back in twi is a complete loss in God's eyes.
