That is what the people of long ago were praised for.
In the past, God spoke to our people through the prophets. He spoke at many times. He spoke in different ways.
All these people were praised because they had faith. But none of them received what God had promised.
Abel had faith. So he brought to God a better offering than Cain did. Because of his faith Abel was praised as a godly man. God said good things about his offerings. Because of his faith Abel still speaks. He speaks even though he is dead.
