What change should be evident in someone who has come to a knowledge of salvation?
A complete change in lifestyle and desire should be evident: things once hated are now loved, and things once loved are now hated. The person walks not after the flesh but after the Spirit, minding the things of the Spirit rather than the old Adamic nature, because that transformation is the whole point of salvation.
Les explains that the evidence is a reversal of affections: the things Paul once hated he now loves, and the things he once loved he now hates. When someone is brought to a knowledge of salvation, Les looks for a complete change in lifestyle and in desire, because that is the whole point. The saved person walks not after the flesh but after the Spirit and minds the things of the Spirit. By contrast, the lost person remains in spiritual darkness, blinded by the God of this world, concerned only with fleshly appetites, materialism, and the things of old Adam.
