For what if some did not believe? – Romans 3:3

In our Saviour’s day, they said, “Have any of the rulers or of the Pharisees believed in Him?” The gospel has usually had a free course among the poor and among those who some call “the lower orders”, though why they are said to be lower than others, I do not know, unless it is because the heavier and more valuable things generally sink to the bottom. The Church of God owes very little to kings and princes and nobles. She owes far more to fishermen and peasants. Jesus said, “I thank Thee, O Father, Lord of heaven and earth, because Thou hast hid these things from the wise and prudent, and hast revealed them unto babes. Even so, Father: for so it seemed good in Thy sight.” I suspect that, until the King Himself shall come, we shall still find that the common people will gladly hear the gospel; and that, while Christ the Lord will choose for His own some from all ranks and conditions of men, it will still be true that “not many wise men after the flesh, not many mighty, not many noble, are called.”

In the days of our Lord and His apostles, the scribes and Pharisees were the greatest haters of the doctrine of Christ. Those whom you might have supposed, being most familiar with the Scriptures, the scribes, would soonest have recognized the Messiah, were the men who would not acknowledge Him. So it was with the priests, even the chief priests, the men who had to do with the sacrifices and with the temple. They rejected Christ, although they were the religious leaders of the people. Do you suppose it is very different now? …Believers are not always those whom you would suppose would be believers…But alas! Alas! Among those who appear to be the children of the kingdom, brought up in the worship of God, there are some, yea, many, who have not believed on Christ; and, saddest of all, even among those who are the teachers of others in the things of God, there are some that have not savingly believed. ~ C.H. Spurgeon
