Strict Calvinism, particularly in its Lordship Salvation expression, teaches that genuine faith inevitably produces a life of obedience, perseverance, and good works, since regeneration precedes faith and imparts a supernatural ability to believe and obey. However, this view confuses justification with sanctification by making ongoing obedience a necessary proof of salvation. Biblically, all people are spiritually dead and totally depraved (Rom 3:10-12; Eph 2:1), yet God’s prevenient grace and the convicting work of the Spirit enable unbelievers to respond freely in faith (John 16:8-11). Faith precedes regeneration (John 3:16; Eph 1:13), and eternal life is a free gift received by grace through faith alone in Christ alone, apart from works (Rom 4:5; Eph 2:8-9). While discipleship involves lifelong obedience and is rewarded, it is not a condition for salvation (1 Cor 3:12-15; 2 Tim 4:7-8). The Lordship view undermines assurance by tying it to performance, rather than to God’s unchanging promise (John 10:28-29; 1 John 5:13).
