It was never God's plan for humanity to exist in isolation. From the very beginning, we see God's triune character creating the world. When humanity was first made, God walked with us in the garden. Even after our sin, He chose to make a way for us to come back into relationship with Him through Jesus Christ. At first He made covenants with Israel, but with the coming of Jesus He made new covenants inviting the all non-Jews into the same family of God. Together, we make up the family of God.
