"adversaries of Judah and Benjamin, come with smooth words and fair speeches, apparently seeking for friendly alliance with God's children, have greater power to deceive. Against such every soul should be on the alert, lest some carefully concealed and masterly snare take him unaware. And especially today, while earth's history is closing, the Lord requires of His children a vigilance that knows no relaxation. But though the conflict is a ceaseless one, none are left to struggle alone. Angels help and protect those who walk humbly before God. Never will our Lord betray one who trusts in Him. As His children draw near to Him for protection from evil, in pity and love He lifts up for them a standard against the enemy. Touch them not, He says; for they are Mine. I have graven them upon the palms of My hands. PK 570.4"
"Beware of false prophets, which come to you in sheep’s clothing, but inwardly they are ravening wolves."
EGW's warning about adversaries with smooth words and fair speeches echoes the warning in Matthew 7:15 about false prophets who appear harmless but are inwardly dangerous.
