Must grace alone by faith alone in Jesus as Lord be supplemented by works of obedience to be saved from death in Hell?
If one suggests they are saved by grace having trusted in Jesus as Lord yet there is no evidence of a changed life or evidence of the fruit of the Spirit in their life (Galatians 5:22-23)…they are a liar and living in self-deception. Jesus said you would know them by their fruit (Matthew 7:15-20).
With that said, you cannot earn or supplement the grace of God with your works before or subsequent to salvation. Obedience to the indwelling Holy Spirit subsequent to salvation is a natural act or resultant of being born again by grace (unmerited favor unattainable by human effort) through faith (trust-belief) in Jesus as Lord.Your obedience to the Commands of Jesus that follow true salvation does NOT supplement faith or grace; obedience subsequent to salvation only validates, substantiates, the fact that true salvation has manifest in one’s life by faith, alone, in Jesus, alone, as Lord, alone.
The good works that follow salvation are not done to complete the salvation process but these works of obedience, righteousness, fruit of the Spirit, are a sign that the salvation process has resulted in covenant relationship with the Father by faith in the Son, Jesus Christ, and those works of obedience are ONLY possible by the Holy Spirit who indwells the believer as Guarantor of covenant relationship that was established by grace, alone, by faith, alone, in Jesus, alone (Galatians 5:16; Ephesians 1:13-14).
