For ye see your calling, brethren, how that not many wise men after the flesh, not many mighty, not many noble, are called… – 1 Corinthians 1:26

When a man wishes the way of salvation to be difficult he naturally kicks at it because it is easy; and, when his pride wants it to be hard to be understood, he is pretty sure to say that he does not understand it because it is so plain. Do not you know that the unlettered often receive Christ when philosophers refuse him, and that he who has not called many of the great, and many of the mighty, has chosen poor, foolish, and despised things? That is because poor foolish men, you know, are willing to believe a plain thing, but men wise in their own conceits desire to be, if they can, a little confounded and puzzled that they may please themselves with the idea that their own superior intellect has made a discovery; and, because the way of salvation is just so easy that almost an idiot boy may lay hold of it, therefore they pretend that they do not understand it. Some people cannot see a thing because it is too high up; but there are others who cannot see it because it is too low down. Now, it so happens that the way of salvation by faith is so simple that it seems beneath the dignity of exceedingly clever men. May God bring them to a knowledge of this truth: may they see that they cannot be saved except by giving up all idea of saving themselves; that they cannot be saved except they step right into Christ, for, until they get to the end of the creature, they will never get to the beginning of the Creator. Till they empty out their pockets of every mouldy crust, and have not a crumb left; they cannot come and take the rich mercy which is stored up in Christ Jesus for every empty, needy sinner. May the Lord be pleased to give you that knowledge of the truth!~ C.H. Spurgeon
