What does Les look for as evidence that someone has been truly saved?
The evidence sought is a complete change in lifestyle and desire: the things once hated are now loved, and the things once loved are now hated. This transformation reflects walking after the Spirit rather than the flesh, confirming genuine salvation.
Les explains that he always looks for this change when he has the opportunity of bringing someone to a knowledge of salvation. He wants to see a complete change in lifestyle and desire, because that is the whole point. The Apostle Paul's testimony—"The things I once hated, now I love; and the things I once loved, now I hate"—illustrates this transformation. Les contrasts the lost individual, who minds the things of the flesh (old Adam), with the saved individual, who minds the things of the Spirit. The lost are blinded by the god of this world and have only fleshly appetites, while the saved walk after the Spirit. Les notes he has seen ungodly people with no spiritual appetite, but true salvation produces a changed desire.
