What does Genesis 15:2 mean?

But Abram said, Lord God, what good are your gifts if I don’t have a child? Right now, Eliezer from Damascus is set to inherit everything I have. Genesis 15:2 - Modern Text Bible

(Abram’s honest with God—he’s grateful, but he longs for a child. He’s worried that his legacy will go to a servant instead of his own family.)
