Matthew Henry's Concise Commentary (MHCC tab in e-Sword if you have downloaded it). E-sword's Commentary download page: http://www.e-sword.net/commentaries.html.
The rejecting of the Jews, and the taking in the Gentiles, were foretold in the Old Testament. It tends very much to the clearing of a truth, to observe how the Scripture is fulfilled in it. It is a wonder of Divine power and mercy that there are any saved: for even those left to be a seed, if God had dealt with them according to their sins, had perished with the rest. This great truth this Scripture teaches us. Even among the vast number of professing Christians it is to be feared that only a remnant will be saved."
Imagine!!!!! How sad! How many people .......... GENERATIONS..........may be surprised when they die, that their profession of faith was not a true one. That they were only playing at Christianity and teaching the next generation to do so as well???? Playing at going to church, sunday school, reading the Bible, going to church socials, insisting kids marry someone of their own faith, praying over Christmas and Easter dinner ...............etc. etc. etc. (all the obligatory outward things - "works") all the while not really being believers in Christ?!?!?
Rev. 20:12: "...and the dead were judged from the things which were written in the books, according to their deeds." (believers in Christ are not, their sins have been washed away by His blood sacrifice)
Gal. 2:16: "...a man is not justified by the works of the Law but through faith in Christ Jesus, even we have believed in Christ Jesus, so that we may be justified by faith in Christ and not by the works of the Law; since by the works of the Law no flesh will be justified."
Ultimately the fault lies within us. It is out of our God-given free will to choose the redemption by the blood of His son or not. He loved us enough to give us the choice, because forced worship is no worship at all. Perhaps the worst thing that ever happened to Christianity is organized religion!!!!!!!!!!! As Dr. Tony Evans has said............"some of the worst Christians are the ones who are in church every time the doors open.......because that is what they think being a 'Christian' is about"!
Jesus was the most UN-religious person who ever walked the face of the earth. He taught in the synagogues, yes.........but by the example of the Pharisees (leaders of the 'church'), He showed us ALL, Christians and Jews alike, that we are to know God and His word ourselves..........NOT simply sit in church week after week listening to some man's dissertation of a few verses, which may even be taken out of context. READ THE BIBLE. Make up your own mind!
Jewish example: Psalm 22 was, in the past, considered by the rabbis as prophetic in nature about the Messiah. However, eventually it was decided by the rabbis that the Christians were onto this, and that it should be de-emphasized. Dr. Chuck Missler covers this in detail in his study on Psalms. Free to hear (his 66/40 radio show) online here - click on part 5. Psalm 22 reads the crucifixion of Jesus as if dictated from the cross!!! It opens and closes with the first and last words spoken by Jesus on the Cross. NOTE: this Psalm was written 600 years before crucifixion was invented by the Persians.
Christian example: By and large today's churches teach the unBiblical view that the church has replaced Israel due to Israel's rejection of their Messiah. WRONG!!!!!!!!!! There are hundreds of Biblical reasons to prove this wrong! To claim this is to call God a liar. The Book of Revelation revolves around Israel! The saved will be singing the song of Moses in heaven!
