Defining the Fallacy: What Is a Non Sequitur?
The Premise and the Gap: A non sequitur (Latin for “it does not follow”) occurs in formal and informal logic when a conclusion is asserted that has no necessary or valid connection to the prior premises.
The Theological Import: In evangelical soteriology, this fallacy routinely surfaces when human obligation is smuggled into the divine gift. The premise may be entirely biblical, but the inferred conclusion creates an unbridgeable logical and theological chasm.
The Great Evangelical Non Sequitur: Confusing the Gift with the Cost
Premise: Jesus Christ demands radical surrender, cross-bearing, and faithful endurance from His disciples (Luke 14:26–33).
Faulty Conclusion: Therefore, an individual must commit to total surrender and cross-bearing in order to receive eternal life.
The Break in the Syllogism: The conclusion simply does not follow. Salvation is a free gift (dōrea) appropriated solely by faith (pisteuō) at a single point in time, whereas discipleship is a costly, lifelong endeavor of obedience. As Hodges (1989) observes in Absolutely Free, confusing the free water of life with the demanding curriculum of Christ’s school turns the gospel upside down. Salvation costs nothing; discipleship costs everything.
The Syntactic Non Sequitur: The Nature of Saving Faith
Premise: Paul declares that believers are created in Christ Jesus for good works (Eph 2:10).
Faulty Conclusion: Therefore, a person whose life currently lacks visible good works was never truly saved and possessed a counterfeit, “dead” faith.
The Grammar of the Text: In Ephesians 2:10, the clause hina en autois peripatēsōmen (“that we should walk in them”) utilizes hina with the subjunctive mood, expressing divine intention and purpose rather than guaranteed, automatic performance. Just as John 3:17 expresses God’s purpose that the world might be saved (hina sōthē) without guaranteeing universalism, Ephesians 2:10 does not guarantee that every believer unfailingly walks in good works.
The Truth of Faith: Faith (pistis) is simple, childlike persuasion that God’s promise in Christ is true (John 6:47; 11:25–27). Concluding that genuine faith must inherently include lifelong perseverance commits an illegitimate semantic transfer.
Restoring the Biblical Distinction: Inheritance versus Possession
Entering the Kingdom: Everlasting life is an irrevocable present possession received the instant one believes the Savior’s promise (John 5:24).
Inheriting the Kingdom: Co-heirship and ruling with Christ are distinct rewards granted to the overcomer who perseveres through testing (Rom 8:17; 2 Tim 2:12; Rev 2:26).
The Ultimate Consequence: An unfaithful believer may suffer severe temporal chastening or forfeit eternal rewards at the Judgment Seat of Christ (bēma), yet “he himself will be saved, yet so as through fire” (1 Cor 3:15).
When we refuse to allow non sequitur reasoning to dictate our hermeneutic, the gospel shines with pristine simplicity: eternal life is absolutely free, while the eternal prize requires our all.
