Paul had previously explained the new covenant in Christ’s blood, that His sacrifice was the propitiation for our sins. That God is just and the justifier of all men through faith in Christ and that there is no distinction with God. For all have sinned and fall short of the glory of God.
27 Where then is boasting? It is excluded. By what kind of law? Of works? No, but by a law of faith. 28 For we maintain that a man is justified by faith apart from works of the Law. 29 Or is God the God of Jews only? Is He not the God of Gentiles also? Yes, of Gentiles also, 30 since indeed God who will justify the circumcised by faith and the uncircumcised through faith is one.
31 Do we then nullify the Law through faith? May it never be! On the contrary, we establish the Law.
V.27 “Where then is boasting? It is excluded. By what kind of law? Of works? No, but by a law of faith.”
This was a common theme that Paul expounded upon in his letters to the churches (1 Cor. 1:29-31, 2 Eph. 2:8-10, Gal. 2:16) and it was consistent with what The Lord taught, “He who believes in the Son has eternal life; but he who does not obey the Son will not see life, but the wrath of God abides on him.” John 3:36
V.28 “For we maintain that a man is justified by faith apart from works of the Law.”
This is the same gospel that Paul proclaimed during his first missionary journey. In the synagogue ay Psidian Antioch Paul declared to the Jews and God fearers, “Therefore let it be known to you, brethren, that through Him forgiveness of sins is proclaimed to you, and through Him everyone who believes is freed from all things, from which you could not be freed through the Law of Moses.” Acts 13:38-39
V.29 “Or is God the God of Jews only? Is He not the God of Gentiles also? Yes, of Gentiles also,”
The prophecy of Zechariah, “Many nations will join themselves to the LORD in that day and will become My people. Then I will dwell in your midst, and you will know that the LORD of hosts has sent Me to you.” Zechariah 2:11
V.30 “since indeed God who will justify the circumcised by faith and the uncircumcised through faith is one.”
“So circumcise your heart, and stiffen your neck no longer. For the LORD your God is the God of gods and the Lord of lords, the great, the mighty, and the awesome God who does not show partiality nor take a bribe. He executes justice for the orphan and the widow, and shows His love for the alien by giving him food and clothing.”
V.31 “Do we then nullify the Law through faith? May it never be! On the contrary, we establish the Law.”
“Do not think that I came to abolish the Law or the Prophets; I did not come to abolish but to fulfill. For truly I say to you, until heaven and earth pass away, not the smallest letter or stroke shall pass from the Law until all is accomplished.”
It is not the outward observance of the law, but the inner observance of the law of love that God acknowledges. When the Pharisees and self religious types accused The Lord of disregarding the law and profaning the Sabbath by plucking a few heads of grain and eating them with unwashed hands he told the crowd.
“It is not what enters into the mouth that defiles the man, but what proceeds out of the mouth, this defiles the man.”
Taking His disciples aside He explained the meaning of His actions and teaching.
Mat 15:18 “But the things that proceed out of the mouth come from the heart, and those defile the man. For out of the heart come evil thoughts, murders, adulteries, fornications, thefts, false witness, slanders. These are the things which defile the man; but to eat with unwashed hands does not defile the man.”
Christ established a new covenant in His blood, a new commandment to love one another, a new law the law of love and liberty.
“A new commandment I give to you, that you love one another, even as I have loved you, that you also love one another. By this all men will know that you are My disciples, if you have love for one another.”
Until our next study may The Lord be with you and keep you in His agape love.
