A relação entre o antigo e o Novo Testamento: como as escrituras se conectam

13-17 So Isaiah told him, "Then listen to this, government of David! It’s bad enough that you make people tired with your pious, timid hypocrisies, but now you’re making God tired. So the Master is going to give you a sign anyway. Watch for this: A girl who is presently a virgin will get pregnant. She’ll bear a son and name him Immanuel (God-With-Us). By the time the child is twelve years old, able to make moral decisions, the threat of war will be over. Relax, those two kings that have you so worried will be out of the picture. But also be warned: God will bring on you and your people and your government a judgment worse than anything since the time the kingdom split, when Ephraim left Judah. The king of Assyria is coming!"

25-27 Then he said to them, "So thick-headed! So slow-hearted! Why can’t you simply believe all that the prophets said? Don’t you see that these things had to happen, that the Messiah had to suffer and only then enter into his glory?" Then he started at the beginning, with the Books of Moses, and went on through all the Prophets, pointing out everything in the Scriptures that referred to him.

1-10 The old plan was only a hint of the good things in the new plan. Since that old "law plan" wasn’t complete in itself, it couldn’t complete those who followed it. No matter how many sacrifices were offered year after year, they never added up to a complete solution. If they had, the worshipers would have gone blissfully on their way, no longer dragged down by their sins. But instead of removing awareness of sin, when those animal sacrifices were repeated over and over they actually heightened awareness and guilt. The plain fact is that bull and goat blood can’t get rid of sin. That is what is meant by this prophecy, put in the mouth of Christ:

You don’t want sacrifices and offerings year after year;

you’ve prepared a body for me for a sacrifice.

It’s not fragrance and smoke from the altar

that whet your appetite.

So I said, "I’m here to do it your way, O God,

the way it’s described in your Book."

When he said, "You don’t want sacrifices and offerings," he was referring to practices according to the old plan. When he added, "I’m here to do it your way," he set aside the first in order to enact the new plan—God’s way—by which we are made fit for God by the once-for-all sacrifice of Jesus.
