NO PEOPLE LEFT OUT
There may have been accusations against Paul’s teaching, claiming that He was preaching an unjust and unrighteous God. That is not what Paul preached, nor is it the teaching of Scripture.
Because God is holy, righteous, and just He has every right to be “Merciful to whom He will be merciful” and to “Have compassion on whom He will have compassion”. He has did everything that His glory, holiness, righteousness, and justness allowed Him to do in order that the lost might be saved.
Hosea’s wife Gomer is brought into this picture of God’s salvation. She had become a harlot, yet God commanded Hosea to love her, and redeem her from her slavery (Hosea 2:1-22; 3:1-5). Paul quotes the prophet Isaiah saying, “Though the number of the children of Israel be as the sand of the sea, a remnant shall be saved: for He will finish the work, and cut it short in righteousness: because a short work will the Lord make upon the earth”. (vv. 27-28; Isaiah 10:22-23). These quotations make it quite plain that God’s intentions has always been to save people from every tribe, tongue, and nation. He has blessed the nation of Israel with the blessing of giving the world His Word and the Living Word [His Son Jesus], and is blessing them again, by bringing them back to Himself, though they have strayed, and not believed Him. (See Isaiah 1:9 and 13:9).
Hosea 2:23 Paul has given as the Word of God for calling people for Himself from the Gentile nations.
Vv. 25-26 — The quotation from Hosea concerning those not “My people” and called “Children of the living God”;
Vv. 27-29 — The numerous number of Israel shows God’s fulfillment to make of them a “Great Nation”, however, due to their unfaithfulness, there will only be a small number (a remnant) from that number who will be delivered; thus, He will finish the things which He has said concerning Israel, and He will fulfill His word in short order. Except the Lord saved a remnant the Nation would have been like Sodom and Gomorrha, in destruction;
Vv. 30-32 — You can almost begin to see that there have been questions concerning the Jews about what Paul is teaching, and he is answering them; “What about these Gentiles who never pursued righteousness, and now are righteous?” It is theirs because of faith, ie., trusting God implicitly, and no other – no works – just a simple faith that realizes that it is solely by grace through faith we are saved. Israel, on the other hand, had the law, pursuing it by their works, and deeds and failed to attain righteousness by the law. The reason Israel failed is they were seeking to obtain it by the keeping of the law, rather than trusting the Lord and His grace; they had not the faith; and when it came to Jesus, their Messiah/Christ, He was a “Stumbling stone”;
v. 33 — In Isaiah 8:14 and 28:16 the prophet tells us basically what Paul is quoting; Jesus, the One who died on the cross to may a way for “His own”, and the nations, was rejected, because the cross was and still is an “Offense”. It is not only an offense to the Jew it is an offense to many who are Gentiles.
In 1993 the Barna Research Group conducted a poll on beliefs among those who professed being born again, as compared to the total population. The statement, “All good people, whether they consider Jesus Christ to be their Lord and Savior or not, will live in Heaven after they die on earth” was read to those who participated. Of those who professed to be “Born again” thirty two percent [32%] agreed with the statement. Forty eight [48%] of those churched agreed, along with forty four percent [44%] of the total population.
“All good people, whether they consider Jesus Christ to be their Lord and Savior or not will live in Heaven after they die on earth.”
Professing Born again …. 32 percent agreed;
Those who attend church …. 48 percent agreed;
Total population …. 44 percent agreed.
It is evident even today  that this has not improved. It has most likely worsened. How terrible it would be to stand before Jesus one day and have our only answer being, “I thought I could make it on my own. I was a good man/woman.” Then, to hear Jesus say, “I never knew you. Depart from me, you worker of iniquity”.
There will be no shame for those who take God at His Word and believe in Jesus. We will be able to stand before Him with confidence in His finished work and all the glory will belong solely to Him, and that will be our glorification.
