What does the Bible say about God's relationship with Abraham?

In Genesis, we see God's relationship with Abraham as one of intimacy and promise. God appeared to Abraham multiple times, demonstrating His desire for fellowship. Notably, in Genesis 15, God reassures Abraham with His covenant promises, and in Genesis 18, He physically comes to Abraham in the form of three men, showcasing the closeness of their relationship. This illustrates that God not only issues commands but seeks a deep, personal relationship with His chosen people, confirming that Abraham's faithfulness is rooted in a covenant established by God Himself.
