As Yourself

Matthew 7:12 ESV 

“So whatever you wish that others would do to you, do also to them, for this is the Law and the Prophets.

Romans 13:9-10 ESV 

9 For the commandments, “You shall not commit adultery, You shall not murder, You shall not steal, You shall not covet,” and any other commandment, are summed up in this word: “You shall love your neighbor as yourself.” 10 Love does no wrong to a neighbor; therefore love is the fulfilling of the law.

Those in the body of Christ share in that one body. We are united with Christ and each other by the one Spirit. What we do to or for another, we do to ourselves and to Jesus.
