I have friends in unsound doctrine churches.
I just encourage them to read the scriptures in context.
My heart is heavy for the lost and for the brethren wallowing in the muck and mire of confusing unsound teaching.
As such was I .. wallowing for years in confusion, wondering why I did not believe the same, why I was not excited over the preaching on material gain, wondering, is there more to God than this.
