The words "Sure word of prophecy" is from the King James.. but The Message translation says it pretty well. We must be careful of what we accept as a Sure Word in this day and hour. Some isn't that sure.
2 Peter Chapter One
16-18 We weren’t, you know, just wishing on a star when we laid the facts out before you regarding the powerful return of our Master, Jesus Christ. We were there for the preview! We saw it with our own eyes: Jesus resplendent with light from God the Father as the voice of Majestic Glory spoke: “This is my Son, marked by my love, focus of all my delight.” We were there on the holy mountain with him. We heard the voice out of heaven with our very own ears.
19-21 We couldn’t be more sure of what we saw and heard—God’s glory, God’s voice. The prophetic Word was confirmed to us. You’ll do well to keep focusing on it. It’s the one light you have in a dark time as you wait for daybreak and the rising of the Morning Star in your hearts. The main thing to keep in mind here is that no prophecy of Scripture is a matter of private opinion. And why? Because it’s not something concocted in the human heart. Prophecy resulted when the Holy Spirit prompted men and women to speak God’s Word.
Chapter 2 1-2 But there were also lying prophets among the people then, just as there will be lying religious teachers among you. They’ll smuggle in destructive divisions, pitting you against each other—biting the hand of the One who gave them a chance to have their lives back! They’ve put themselves on a fast downhill slide to destruction, but not before they recruit a crowd of mixed-up followers who can’t tell right from wrong.
2-3 They give the way of truth a bad name. They’re only out for themselves. They’ll say anything, anything, that sounds good to exploit you. They won’t, of course, get by with it. They’ll come to a bad end, for God has never just stood by and let that kind of thing go on.
I'm not looking to stone anyone, just be more careful.. PLEASE!
