Scripture indicates, those in heaven are aware of the prayers of those on earth. This can be seen, for example, in Revelation 5:8, where John depicts the saints in heaven offering our prayers to God under the form of "golden bowls full of incense, which are the prayers of the saints." But if the saints in heaven are offering our prayers to God, then they must be aware of our prayers. They are aware of our petitions and present them to God by interceding for us.
