The four living creatures and the twenty-four elders fell down before the Lamb, each one holding a harp and golden bowls full of incense, which are the prayers of the saints.
Our prayers don’t fly up to God’s ear and dissipate. He values our prayers and collects them in golden bowls.
Perhaps there is a bowl for each of us, a bowl engraved with our name, that holds all the prayers ever offered on our behalf. When you pray for someone, your prayer is held in that bowl as a sweet fragrance before the Lord.
