Drew,
I think there can be middle ground.
If one believes the Bible that Abraham’s seed is the means that all nations of the earth bless themselves. It might trouble some that Abraham had significant flaws. He apparently, (1) lied about his relationship with Sarah (although many would have done the same), lived and associated with his father Terah who worshipped a pagan God and (3) directly questioned Jehovah regarding the destruction of Sodom.
So obviously he at times had what some would call errors in judgment. Did that mean that he was not God’s means for blessing mankind? Of course not! On balance the Bible describes him as God’s friend.
Today the WT is teaching what I feel is the truth about (1) the mortality of the human soul, (2) the monotheism of Jehovah, (3) the resurrection and (4) the ransom and God’s purpose for the earth. Do they also teach things that have proved to be false? Yes!. But no other religion that I know of has the core issues right.
Did God let men such as Eli, Manaseh, Saul, Judas and others serve? The Bible suggests that He did. Does this mean that the nation of Isreal was not God’s channel? Or does it mean that Jesus is not God’s son since he messed up in choosing Judas? I don’t believe that to be the case.
So bottom line, I feel that God has a channel and that channel has proved to be very flawed. Until I can find a better channel I am sticking with this one and will await His instruction.
