What is the problem with favouritism and partiality? It is lack of love. It is using people for our own ends. They are tools for our own advancement…instead of investing in them for the sake of the kingdom and for their good. Who has God called upon you to invest in for their sake, for their good, for their sanctification, and for your joy? Not to strengthen our egos, but to strengthen them in the Lord.1
Thomas Schreiner
8 If you really fulfill the royal law according to the Scripture, “You shall love your neighbor as yourself,” you are doing well.
