11:14 angel of light. Satan originally was the highest of all the angels (see notes on Isaiah 14:12-15 and Ezekiel 28:12-15), and he still has great authority (note Jude 9) and power to produce great “signs and wonders.” These, however, are “lying wonders” (II Thessalonians 2:9), intended, “if it were possible…[to] deceive the very elect” (Matthew 24:24). One must always test such pretenders by their faithfulness to the inerrant Word of God and the full deity and sinless humanity of Jesus Christ, as well as their genuine Christian character and behavior. It was such a false “angel of light” who has deceived many founders of false religions (Mohammed, Joseph Smith, etc.).

11:15 ministers of righteousness. There are many who profess to be servants (i.e., “ministers”) of righteousness, even appearing on occasion to work miracles, but these in themselves prove nothing. “He that doeth the will of my Father” (Matthew 7:21)—that is the test, according to Jesus. “Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? And then I will profess unto them, I never knew you: depart from me, ye that work iniquity” (Matthew 7:22-23).

11:15 their works. Perhaps here Paul was also alluding to those Judaizers who were demanding that Christians adhere to the righteousness of the Law in order to attain salvation, undermining the great doctrine of salvation by grace. But those who seek salvation by works must then be judged by their works, and none can measure up to the divine standard (Galatians 2:16). All who are judged “according to their works” shall be “cast into the lake of fire” (Revelation 20:13, 15).
