Justification of Life

“By the righteousness of One the free gift came upon all men unto justification of life.” There is no exception here. As the condemnation came upon all, so the justification comes upon all. Christ has tasted death for every man. He has given Himself for all. Nay, He has given himself to every man. The free gift has come upon all. The fact that it is a free gift is evidence that there is no exception. If it came upon only those who have some special qualification, then it would not be a free gift. It is a fact, therefore, plainly stated in the Bible, that the gift of righteousness and life in Christ has come to every man on earth. There is not the slightest reason why every man that has ever lived should not be saved unto eternal life, except that they would not have it. So many spurn the gift offered so freely. 

By the obedience of One shall many be made righteous. Men are not saved through their own obedience, but through the obedience of Christ. Here is where the skeptic cavils, and says that it is not just that one man's obedience should be counted as another’s. But the man who rejects the counsel of the Lord does not know anything about justice, and is not qualified to speak in the case. The Bible does not teach us that God calls us righteous simply because Jesus of Nazareth was righteous eighteen hundred years ago. It says that by His obedience we are made righteous. Notice that it is present, actual righteousness. The trouble with those who object to the righteousness of Christ being imputed to believers is that they do not take into consideration the fact that Jesus lives. He is alive today, as much as when He was in Judea. “He ever liveth,” and He is “the same yesterday and to-day, and forever.” His life is as perfectly in harmony with the law now as it was then. And He lives in the hearts of those who believe on him. Therefore it is Christ’s present obedience in believers that makes them righteous. They can of themselves do nothing, and so God in His love does it in them. Here is the whole story: “I am crucified with Christ; nevertheless I live; yet not I but Christ liveth in me; and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave Himself for me” (Gal. 2:20).

The text says, “By the obedience of One shall many be made righteous.” Some one may ask, “Why are not all made righteous by the obedience of One?” The reason is that they do not wish to be. If men were counted righteous simply because One was righteous eighteen hundred years ago, then all would have to be righteous by the same obedience. There would be no justice in counting righteousness to one and not to all, if it were in that way. But we have seen that it is not so. People are not simply counted righteous, but actually made righteous, by the obedience of Christ, who is as righteous as He ever was, and who lives today in those who yield to Him. His ability to live in any human being is shown in the fact that he took human flesh eighteen hundred years ago. What God did in the person of the Carpenter of Nazareth, He is willing and anxious to do for every man that believes. The free gift comes upon all, but all will not accept it, and therefore all are not made righteous by it. Nevertheless, “many” will be made righteous by His obedience - who will be one of the many?
