This passage discusses prayer, sin, and God's providence. It encourages believers to pray according to God's will and for fellow believers who sin, with the exception of the sin of apostasy which leads to death. While all wrongdoing is sin, God protects those born of God from the evil one and empowers them to resist sin. The world remains under the control of the evil one, so believers must avoid idolatry and put their trust in Jesus Christ as the true God who gives eternal life.
