Spurgeon on Obedience

When we find His law written either in the Ten Commandments or anywhere else, we believe that there is not one precept too many or too few. Whatever the precepts of the law or the Gospel may be, they are pure and altogether holy. The words of the Lord are like “fine gold” (Psalm 19:10), pure, precious, and weighty—not one of them may be neglected.
We hear people talking about “minor points of the law” [note: today they say "non-essential doctrines"]and so on. However, we must not consider any word of our God as a minor thing if, by that expression, it is implied that it is of small importance. We must accept every single word of precept or prohibition or instruction as being what it ought to be, neither to be diminished nor increased.
We should not reason about the command of God as though it might be set aside or amended. He commands; we obey. May we enter into that true spirit of obedience, which is the unshakable belief that the Lord is right! Nothing short of this is the obedience of the inner man—the obedience that the Lord desires
