This topic is so comprehensive. You and I were made for relationships. This fact takes us back to the beginning. It asks the basic questions, “Who are we, and how important are our relationships?”
In Genesis 2:18, God says that it is not good for man to be “alone.” This statement has more to do with God’s design for humanity than Adam’s neediness.
God created us to be relational beings because He is a social God. God lives in community within the Trinity as Father, Son, and Holy Spirit, and He made humanity in His image.
Genesis 2 is not speaking primarily to Adam’s experience of being lonely, as much as it is revealing his nature as the person God created him to be. Because God created a communal being—someone designed for relationships, creation is incomplete without a suitable companion!
