Is salvation by faith plus anything else?
No, salvation is by faith plus nothing, apart from human energy or human merit. No additional condition, work, or effort contributes to it. Adding anything to faith makes the message false. The words 'who walk not after the flesh, but after the Spirit' do not belong in verse 1 and cannot be used to require such walking for salvation.
Les teaches that salvation is faith plus nothing. He emphasizes that no human energy and no human merit can be added to faith. He explains that the phrase 'who walk not after the flesh, but after the Spirit' does not belong in verse 1; the earliest manuscripts do not have it, and Bible scholars agree it is an error there. If left in verse 1, it would make salvation depend on not walking in the flesh but walking in the Spirit, which is not how anyone got into the Body of Christ. Those words belong down in verse 4, where they describe the walk of those already in Christ, not the means of salvation.
