R.A. Torrey emphasizes the power of praying in the name of Christ and according to God's will, illustrating that true prayer is not based on our merit but on Christ's. He explains that praying in Jesus' name means approaching God with His authority, much like presenting a check signed by someone with sufficient funds. Torrey also highlights the importance of knowing God's will through Scripture and the Holy Spirit, asserting that when we pray according to His will, we can have confidence that our requests will be granted. He encourages believers to study the Word to find God's promises and to pray with unwavering expectation. Ultimately, Torrey calls for a faith-filled approach to prayer that discards uncertainty and embraces the assurance of God's responses.
