For the whole Law [concerning human relationships] is fulfilled in one precept, “You shall love your neighbor as yourself [that is, you shall have an unselfish concern for others and do things for their benefit].”

But the fruit of the Spirit [the result of His presence within us] is love [unselfish concern for others], joy, [inner] peace, patience [not the ability to wait, but how we act while waiting], kindness, goodness, faithfulness,

Now concerning brotherly love, you have no need for anyone to write you, for you have been [personally] taught by God to love one another [that is, to have an unselfish concern for others and to do things for their benefit].

If, however, you are [really] fulfilling the royal law according to the Scripture, “You shall love your neighbor as yourself [that is, if you have an unselfish concern for others and do things for their benefit]” you are doing well.
