This message on 1 John 5:13–21 explores the believer’s certainty in Christ. Rather than living in spiritual doubt, John repeatedly reminds us, “we know”—we know we have eternal life, we know God hears our prayers, and we know Christ protects His people. True knowledge of God produces confidence in prayer, victory over sin, and discernment against idols, calling us to rest in Christ and guard our hearts from anything that would replace Him.
