To the OP.
Saved are those whose names are written into the Will (New Covenant).
Hebrews 9:15-20,24,27-28
That is why he is the one who mediates a new covenant between God and people, so that all who are called can receive the eternal inheritance God has promised them. For Christ died to set them free from the penalty of the sins they had committed under that first covenant. Now when someone leaves a will, it is necessary to prove that the person who made it is dead. The will goes into effect only after the person’s death. While the person who made it is still alive, the will cannot be put into effect. That is why even the first covenant was put into effect with the blood of an animal. For after Moses had read each of God’s commandments to all the people, he took the blood of calves and goats, along with water, and sprinkled both the book of God’s law and all the people, using hyssop branches and scarlet wool. Then he said, “This blood confirms the covenant God has made with you.”
For Christ did not enter into a holy place made with human hands, which was only a copy of the true one in heaven. He entered into heaven itself to appear now before God on our behalf.
And just as each person is destined to die once and after that comes judgment, so also Christ died once for all time as a sacrifice to take away the sins of many people. He will come again, not to deal with our sins, but to bring salvation to all who are eagerly waiting for him.
