Prayer is a major biblical topic. The Bible teaches readers the nature, purposes, intentions, and practical applications of prayer in diverse circumstances and situations. The Bible presents different expressions of prayer, major examples of prayers, presuppositions of prayer, various types of prayer, God's diverse answers to different prayers in different circumstances, and nonverbal gestures about prayer. This book attempts to deal with difficult issues such as imprecation or curse prayers, address controversial biblical passages and concepts such as Ps 51 or Rom 8:26-27, and emphasize important similar connections between different biblical texts such as 1 Sam 2:1-10, Ps 113:5-9, Luke 1:46-55, 2 Sam 7:18-29, or 1 Chr 17:16-27.
