Romans 13: 8-10
8 “Let no debt remain outstanding, except the continuing debt to love one another, for he who loves his fellowman has fulfilled the law.
9 The commandments, “Do not commit adultery”, “Do not murder”, “Do not steal”, “Do not covet”, and whatever other commandments there may be, are summed up in this one rule; “Love your neighbour as yourself”.
10 Love does no harm to its neighbour. Therefore love is the fulfilment of the law.
It is not easy to love your neighbour as you love yourself, unless you are in Christ Jesus does it make sense. Even as Christians, Paul says we have to practice hospitality. The kingdom of God is of righteousness, peace and joy in the Holy Spirit. When we walk in love we won’t want to harm our neighbour and break any commandment. As Christ is the end of the law Romans 10: 4, love is the fulfilment of the law. The Jews obtained righteousness through the law by works, but now both Jew and Gentile can obtain righteousness through faith in Christ Jesus.
Romans 9: 30-32
30 “What then shall we say? That the Gentiles, who did not pursue righteousness, have obtained it, a righteousness that is by faith;
31 but Israel, who pursued a law of righteousness, has not attained it.
32 Why not, Because they pursued it not by faith but as if it were by works.
