Hebrews 10:27

Heb. 10:27. But a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries.

In the "Perseverance of the Saints" Edwards deals with this verse commonly adduced as opposed to that doctrine:

§ 32. As to the objections from such hypothetical propositions as those, Hebrews 10:27, etc., "If we sin willfully, after we have received the knowledge of the truth;" Heb. 6:4, etc., "For it is impossible for those who were once enlightened, if they fall away," etc. Such hypothetical propositions may be true, when one or both parts of it are impossible, as the truth of such a proposition consists in the connection of the antecedent and consequent; as when our Lord said to the Jews, "If I should say, I know him not, I should be a liar like unto you." See Gill against Whitby, Vol. I. page 271.

§ 33. Objection. That we are required to take CARE and to PRAY that we may persevere. It was impossible for Christ to fail under his trials; and yet how evident is it that he used means, endeavors, care, labor, and earnest prayers, that he might persevere?
