What does Genesis 15:2 mean?

Up to this point in Abram's relationship with God, we have seen him silently receive the promise that his descendants would become a great nation. Now, after receiving another assurance, Abram speaks back to God. His current heir is a servant, not a son. He boldly—but respectfully—says to the Lord, "What will you give me?" Though it sounds like a complaint, Abram's question is built on his faith in God's power and promises. Abram believes God, but he cannot yet see a path to the things God has promised. Instead of ceasing to believe, Abram takes the opportunity to ask his hard question to the source of his hope.

Sometimes asking a hard question in prayer is the most faithful step a believer can take. Acknowledging our own limitations to God, while asking for His wisdom, is a much better approach than suffering in silence or ignorance. At times, admitting that we cannot understand God's plan is part of submitting ourselves to it. As we'll see through Abram's example, God is always fully faithful to keep His Word.
