Blood-coin for the Wisdom

Listened in on a little of church news on youtube.com. "To preach prosperity, or not teach prosperity, that is the question." Well, no, it isn't. A bishop somebody offered that we must bring an offering with us: "Do not appear before the Lord empty-handed." Amen, bro.. But THAT is an illustration of the spiritual-literal, which is CONSCIOUSNESS. When we pray, we are to have our spiritual-literal sacrificial offering in hand. What, pray tell, might that be? May I offer listening-practice? That we hear and obey?
