Abram's response is a model of honest prayer — he brings his deepest fear and unmet longing directly to God. The ache of childlessness is at the heart of his life. Eliezer of Damascus was his head servant and would be his heir by default without a biological son. Abram is not in rebellion — he is in honest conversation.
Memory phrase: We can be honest with God about what hurts.
Talk about it: Abram told God exactly what was worrying him. Is it okay to tell God what you are sad about or what you wish for? Why?
Prayer: God, I want to be honest with You. Here is what I am waiting for and what I am scared about — I trust You with all of it.
