The truth speaks for it self, we see the true spirit of Christs love and forgiveness in the ones who have a loved one killed, and then they have the ability that passes the naturals mans heart to except, they release the hate, revenge, anger, bitterness, etc.. and can turn that into true Love for the one who did the evil deed.
There is no mystery to where this doctrine is spawned from, and it didn't come from the heart of the spirit.
They can claim bible and scripture till their hell is froze, write mountains of flowery theology based on love
, but have no clue concerning the love of Christ! they have a false christ a false perception of the Most Highs Heart, they can no longer hear the still small voice hidden in the scripture, maybe at one time they felt that unconditional love when they first met Christ within, but that voice has been silenced by their roaring lions of dog-ma.
