There are those, even among Christ’s followers, that are worse than any one can imagine them to be, and lack nothing but opportunity to show it.” (Matthew Henry)
Matthew Henry, that great preacher and Bible Commentator of old, made this statement as he was commenting on Judas’ betrayal of Christ as set out in Matthew 26. I suppose that one reason the Lord included the details of Judas’ betrayal in Scripture was to educate us not to be naive. Judas! And the rest of the disciples, that inner circle of the 12, were shocked when Jesus told them one of them would betray Him.
