Charles Spurgeon Commentary Hebrews 3:11-12

"As I sware in my wrath, They shall not enter into my rest. Take heed, brethren, lest haply there shall be in any one of you an evil heart of unbelief, in falling away from the living God:" — Hebrews 3:11-12 (ASV)

So I sware in my wrath, They shall not enter into my rest. Take heed, brethren, lest there be in any of you an evil heart of unbelief, in departing from the living God.

There was that "evil heart" in the Israelites; is there not a danger that it may be in you also, who are partakers of the same nature?
