Many here are familiar with the current Watchtower doctrine that Jesus is the mediator for only the 144,000.
Members of the great crowd who know and believe WT doctrine on this subject will deny that Jesus Christ is their mediator.
Those of the remant who know and believe WT doctrine on this subject will claim to have Jesus Christ as their mediator, but will deny that the mediator is a man.
However, the Bible says that the mediator is . . . . "the man" Christ Jesus:
"For there is one God, and one mediator between God and men, the man Christ Jesus; Who gave himself a ransom for all, to be testified in due time." 1 Timothy 2:5-6
It seems that all informed JW's (that is those who know and believe WT doctrine on this subject) will deny that there is now a man in heaven as their mediator.
Do you have the man Christ Jesus as your mediator?
