The Bible teaches that believers are many individuals making up one whole body. We are different colors, ages, and genders, but still, we are one with God.

Ephesians 4:4-6
There is one body, and one Spirit, even as ye are called in one hope of your calling; One Lord, one faith, one baptism,
One God and Father of all, who is above all, and through all, and in you all.
