Matthew 7:16

Shall know. Gr. epiginosko, “to know fully.” The metaphor changes; the “sheep” are not entirely unprotected — it is within their power to detect the “wolves” by their bearing and by the way they act. The appealing claims these false prophets set forth are no proof of their true character. Their fair words and exalted profession are no valid test of what they really are, nor can their miracles (v. 22) be depended on. The words “you will know them” may be taken as a promise that the “sheep” who know their Shepherd’s voice (John 10:4) will not be deceived by the fair words of the “wolves” (see 5T 233). Those who truly love the Lord and are fully surrendered to His will need have no fear of being led astray if they obey the voice of God speaking to their souls day by day through His Word and through the counsels He has given (GC 598; 8T 298).

In the great hour of testing that lies ahead, only those who know the truth and love it will be secure against the deceptions of Satan (Hosea 4:6; 2 Thess. 2:9, 10; 6T 401). Compare Matt. 12:33-35; Luke 6:43-45.

Gather grapes of thorns. Compare James 3:11, 12.
