Salvation through the forgiveness of sins. Jesus=>Then he took a cup, and when he had given thanks, he gave it to them, saying, “Drink from it, all of you. 28This is my blood of the covenant, which is poured out for many for the forgiveness of sins.So you are implying that (salvation) here means
Jesus Dying on the cross for the penalty of sin for His chosen, and by this, (that salvation) of Him dying for the Jews that, this will tranfer to the gentiles?
In your words using scripture as reference:
What is his "salvation" that may reach the ends of the earth?
Col 1:19-20
For God was pleased to have all his fullness dwell in him, 20 and through him to reconcile to himself all things, whether things on earth or things in heaven, by making peace through his blood, shed on the cross
Has not the gospel message been made plain to all nations?
