Perseverance: Is Obedience Necessary? | dr. Tom Schreiner

Tom Schreiner argues that the New Testament consistently teaches that Christians must persevere in faith to be finally saved. Contrary to some evangelistic clichés (“You’re saved no matter what you do now”), Scripture never assures converts this way. Instead, early Christian leaders—Barnabas, Paul, Peter, Jude—regularly exhorted believers to continue, stand firm, keep themselves in God’s love, and remain in the faith.Schreiner surveys warnings throughout the New Testament: Jesus warns that only those who endure to the end will be saved; Paul warns the Galatians that receiving circumcision means being “severed from Christ”; Romans 11 warns Gentiles they will be “cut off” if they do not continue in God’s kindness; Hebrews repeatedly warns that falling away leads to judgment. These warnings are real, serious, and addressed to believers about salvation—not merely rewards.Yet perseverance is not perfection and not works-righteousness. Christians still sin, struggle with desires, and grow gradually. Perseverance flows from faith and is empowered by the Spirit, not by human merit.Schreiner’s key thesis: God preserves His elect by means of warnings. The warnings do not imply the elect may finally perish; instead, God uses them as instruments to keep His people trusting Christ to the end. The warnings call not to introspection but to ongoing faith and obedience.
