No race is superior to another race.  We are all made in the divine likeness.  We are all humans designed by a loving Creator to love each other.  True, there are skin and cultural differences, but the God who bridged all gaps to come to us in Christ has modeled what we must do and be for all human beings.  Instead of deeming ourselves better, we are to deem all others as better than ourselves (Philippians 2:3-4).   We are not to lord it over anyone, but we are to make ourselves the servants of all.  Find ways to love and serve and see what happens to your heart.  If we sit where others sit until we feel what they feel, then we will wonder at our past thoughtlessness.
