Q. Where did Jesus get the info that we saints will be like angels? None of the current cannon books address this point.
A. First, in Isaiah 28:10 & 13, Jesus reveals to us, for the FIRST time, His strategy in releasing knowledge, wisdom and understanding to humanity. He has been doing this since Adam and Eve, in both the spiritual AND physical realms. Remember how Einstein reportedly received most or all of his ‘brilliant’ insights?? Remember, Colossians 2-3? Thus, I conclude ALL/EVERYTHING mankind has ever, and will ever learn, COMES FROM JESUS, The Lord God!
Second, In Daniel 12:3, an angel gives us a hint, a signal, that we, The Lord’s righteous saints, will effectively, be shining LIKE THEM – i.e., like The Lord showed Himself, His Glory on the mount of transfiguration. John later confirms this in 1 John 3:2.
Third, Zechariah 12:8 states David, then in his immortal state, will be LIKE AN ANGEL as he rules over all post-apocalyptic Jews in the greatly expanded Israel during The Millennial Reign age.
Ergo, what Jesus correctly said in Matthew 22:30, and confirmed in Mark 12:25, was ‘seeded’ in OT prophecies. I imagine some folks will read these verses and erroneously conclude, ‘WE WILL BE ANGELS!!!’. Such folks might either conveniently forget, or not be aware that, as we understand it, Jesus NEVER invites/invited any angel to do what He invites us to do in Ephesians 2:6 and Revelation 3:21! For more on this point, see: Lost Angels Not for Like-Angels, in which I address the question, In what ways will we be LIKE versus UNLIKE angels?
Finally, I suspect most Christians may be unaware of a significant error in the literal translation of Psalm 8:5, one The Lord apparently allowed. Most translations say humans were created below angels. (See: Ye Are gods! (Series)) It’s so very sad that, though we were created ‘a little lower than God, Himself’ (see: Young’s Literal Translation), folks bow to, serve, and ACT LIKE devils and demons, thus worshiping them as false gods! That explains ALL the wickedness and deep corruption across the entire Earth. As a result, The Lord promises, in Revelation 20, such folks will receive the same, exact, eternal judgment He has reserved for all devils and demons — disgraced former angels who, long ago, rebelled against Him. Both of these groups, as immortal beings, will be cast into a lake of fire that burns eternally with brimstone, likely somewhere on the new Earth The Lord promised to create. (See: The Lake of Fire: A Preview (Series) and Earth’s Next Versions (Series)) And guess who Revelation 19 predicts will be the FIRST two, immortal humans to be cast therein, well over a thousand years before all devils and sinful humans who served them in this life?!
