Those with a heavenly hope are called Christ’s “brothers” (Heb 2:17)
Those with an earthly hope, his children (Isa 9:6) (Now Jesus is our heavenly father?)
Jesus’ sacrifice opened the way for you to have a precious relationship with your loving heavenly Father (I thought my heavenly Father was Jesus?)
This is an interesting point - I don't ever recall seeing any explicit reference to Jesus being the "father" of anyone.
This sounds an awful lot like a step in a trinitarian direction - it will at the very least be very confusing for the 10% or so of JWs who actually pay attention to the talk.
Not likely that the Society will turn trinitarian - more likely just sloppy editing (so what else is new?).
