"Take care, brethren,
lest there be in any of you..."
This lumps us right along with these Jewish Hebrews who were written to in this book of the Bible, so...
"Take warning by those disobedient Israelites...Ye have been brought from the bondage of sin, and have a most gracious promise of an everlasting inheritance among the saints in light; through unbelief and disobedience they lost their rest, through the same ye may lose yours. An evil heart of unbelief will lead away from the living God. What was possible in their case, is possible in yours."
