“I have two friends who have told me that angels have told them certain things. Is this possible? What do the Scriptures say?”
“Do not neglect to show hospitality to strangers, for by this some have entertained angels without knowing it” (Hebrews 13:2; New American Standard Bible)
God seems to leave the impression that angels might still be around and be active. Whether they speak or not, the New Testament doesn’t say. But the Bible does say how to weigh the words of any person or being. . .
“But even if we, or an angel from heaven, should preach to you a gospel contrary to what we have preached to you, he is to be accursed!” (Galatians 1:8)
In other words, even if angels could speak today, they should be judged not by how their words sound, but by how those words stack up against the revealed will of God. Even if angels spoke today, they should be judged according to the Word of God. Whatever a person or angel might say, the Bible is the ultimate authority for hearing and knowing the will of God.
