I have long ways remembered the scripture: Jehovah's eyes are roving about the earth searching for anyone whose heart can be complete towards him" And that Jehovah wants to show his strength in behalf of those who fear him", In a true sense Christ is our new father (Adam) he replaced him, his sacrifice even covers his (Adam's) sin for Christ died for all mankind. Basically I feel as the scriptures indicate that Jehovah is full of tender mercies", and I have always enjoyed this: Jehovah realizes we are mere dust," yet he sent his son to die in our behalf that we could have life through Christ balancing his scales of justice, in a true sense Christ is our new father, his powerful sacrifice even covers Adam's first sin, for as the the bible says Christ died for all mankind.
No where in the scriptures does it say that father Adam and mother Eve can not benefit from Christ sacrifice, that is a Jehovah's Witness doctrine not a bible teaching.
