I'm not sure what you mean by "asleep" but here are some verses about the departed faithful and their activities:
They keep an eye on us:
Heb:12:1: "And therefore we also having so great a cloud of witnesses over our head, laying aside every weight and sin which surrounds us, let us run by patience to the fight proposed to us"
They know about us:
Lk:15:7 "I say to you that even so there shall be joy in heaven upon one sinner that doth penance, more than upon ninety-nine just who need not penance."
They speak to the Lord:
Rv:6:9: "And when he had opened the fifth seal, I saw under the altar the souls of them that were slain for the word of God and for the testimony which they held. 10 And they cried with a loud voice, saying: How long, O Lord (Holy and True), dost thou not judge and revenge our blood on them that dwell on the earth?
Mk:9:4: "And there appeared to them Elias with Moses: and they were talking with Jesus."
They adore God:
Rv:4:10:"The four and twenty ancients fell down before him that sitteth on the throne and adored him that liveth for ever and ever"
They present our prayers to God:
Rv:5:8: "And when he had opened the book, the four living creatures and the four and twenty ancients fell down before the Lamb, having every one of them harps and golden vials full of odours, which are the prayers of saints."
You do realize that the prayers of the saints are OUR prayers, not Catholic saints. M
