We believe that assurance is of "the essence of saving faith." That is, the immediate moment one believes in Christ for the free gift of eternal life, one cannot lack assurance or expect works to prove their salvation, for this is not assurance based on faith in Christ. Assurance improperly placed on works becomes no assurance since believers will never be perfect in all practical sense. Therefore, those who initially lack complete assurance at the moment of saving faith did not believe the gospel offer of Christ because Scripture only knows two adequate responses to accept the free offer of eternal life. Either Christ's claim to give eternal life is believed, or it's not. There is no such thing as having 99% (or less) assurance. This would simply mean one has not understood the simple gospel that promises eternal life for anyone who simply believes Christ. This is why we believe it's the privilege, not only of some, but of all who are born again by the Spirit through faith in Christ as revealed in the Scriptures, to be assured of their salvation from the very moment they take Him to be their Savior and that this assurance is not founded upon any fancied discovery of their own worthiness or fitness, but wholly upon the testimony of God's very Word, the Bible. This should excite within His children filial love, gratitude, and obedience (John 11:25-27; Luke 10:20; 22:32; 2 Corinthians 5:1, 6-8; 2 Timothy 1:12; Hebrews 10:22; 1 John 5:13).
