The proof is in the youth

Isaiah 40:27-31

27 Why sayest thou, O Jacob, and speakest, O Israel, My way is hid from the Lord, and my judgment is passed over from my God?

28 Hast thou not known? hast thou not heard, that the everlasting God, the Lord, the Creator of the ends of the earth, fainteth not, neither is weary? there is no searching of his understanding.

29 He giveth power to the faint; and to them that have no might he increaseth strength.

30 Even the youths shall faint and be weary, and the young men shall utterly fall:

31 But they that wait upon the Lord shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint.

God recognized that the beauty of what He wants to do is going to be poured out on His people, but that even young people would recognize their need for Him. When young people choose the Lord, then you know that the Lord wants to send revival to His people.

He strengthens His people. When God starts stirring the younger generation, we need to pay attention to the proof that God is sending revival through the youth.
