The scripture in 1 John says that if we pray in accordance with God's will, He hears us. And if we know God hears us, then we know we have the petitions of our hearts have been granted. But how do we know what to pray for? According to Brother Duane, we need to learn to pray God's will, and God's will is His Word. When we pray in accordance with God's will, He takes pleasure in answering our prayers. This not only brings glory to Him but also serves as a testimony to non-believers.
